Theories of political conflict or division (such as the ever-popular “tribalism”) that assume irrationality as the source of such conflict, rather than contradictory and/or incompatible sets of recognizable interests and real positions of power, are silly and wrong

Also generally used as justifications for colonial violence, even among leftists. See “Israel and Palestine have been fighting forever sooooooo” or “indigenous tribes naturally fought each other pre-colonization”

Ancient Persian Freezers —- The Yakhchals

Today in the modern world we take freezers, and the frozen results of freezers for granted.  But in ancient times, cold drinks, frozen desserts, and chilled tropical cocktails were a luxury unknown to most people.  However the idea of artificially freezing goods is nothing new.  As far back as 400 BC, the ancient Persians built special freezers called yakhchals.  Yakhchals were large buildings used for storage of ice and foodstuffs during the hot Persian summers.  Typically they were around 60 feet tall, and had a large subterranean storage space dug out from under it.  The Yakhchal itself was made from a special type of mud clay called sarooj which was composed of clay, sand, lime, goat hair, egg whites, and ash mixed in a special proportion which made it extremely resistant to heat transfer.  In other words the inside stayed cool, while heat from the outside was prevented from entering the building because of the thick insulated walls.  This combined with the subterranean storage ensured that whatever goods were stored in the pit stayed cool, as temperatures below ground level are usually around the 60 to 65 degree Fahrenheit range.  However, these designs were not what made a yakhchal a freezer.  There was one other brilliant design feature which ensured that the yakhchal would stay frosty all year long.

At the top of the dome was a small hole, or series of small holes called windcatchers.  Typically windcatchers were pointed in the direction of the prevailing winds.  Due to its conical shape there was always a negative pressure gradient inside the yakhchal.  According to Bernoulli’s Law air flow at a high pressure will always move toward areas of low pressure.  Thus air from the outside was constantly flowing through the yakhchal.  In addition, according to Venturi’s Principal, whenever air flows through a small hole, the smaller the hole, the greater the speed of the flow.  The small hole, or series of holes of the yakhchal ensured that air passed into it at great flows.  What resulted was a great amount of outside air entering into the yakhchal at high speeds.  While the air itself wasn’t cool, the flows at which it was being entrained into the yakhchal created temperatures that were below freezing. Typically the windcatchers were cut in such a way that the incoming jet of air would be directed onto the storage pit.

The ancient Persians primarily used their yakhchals for storing ice and foodstuffs.  During the summer, Persian nobles often enjoyed a frozen treat called faloodeh (pictured above), which is made from thin noodles with syrup made from sugar and rose water, then flavored with lemon, lime, fruits, almond, pistachio, and other flavorings.  Due to the Persian’s freezing technology, faloodeh (which is still popular today) goes down in history as one of the first frozen desserts.  The practice of building and using yakhchals continued up to the 20th century, when they were eventually replaced with modern freezers and refrigerators.

Ancient technology can be really cool…

America is Regressing into a Developing Nation for Most People

This is a good article.

We have entered a phase of regression,and one of the easiest ways to see it is in our infrastructure: our roads and bridges look more like those in Thailand or Venezuela than the Netherlands or Japan. But it goes far deeper than that, which is why Temin uses a famous economic model created to understand developing nations to describe how far inequality has progressed in the United States. The model is the work of West Indian economist W. Arthur Lewis, the only person of African descent to win a Nobel Prize in economics. 

In the Lewis model of a dual economy, much of the low-wage sector has little influence over public policy. Check. 

The high-income sector will keep wages down in the other sector to provide cheap labor for its businesses. Check. 

Social control is used to keep the low-wage sector from challenging the policies favored by the high-income sector. Mass incarceration – check. 

The primary goal of the richest members of the high-income sector is to lower taxes. Check. 

Social and economic mobility is low. Check.

Temin says that today in the U.S., the ticket out is education, which is difficult for two reasons: you have to spend money over a long period of time, and the FTE sector is making those expenditures more and more costly by defunding public schools and making policies that increase student debt burdens.  

Even with a diploma, you will likely find that high-paying jobs come from networks of peers and relatives. Social capital, as well as economic capital, is critical, but because of America’s long history of racism and the obstacles it has created for accumulating both kinds of capital, black graduates often can only find jobs in education, social work, and government instead of higher-paying professional jobs like technology or finance— something most white people are not really aware of. Women are also held back by a long history of sexism and the burdens — made increasingly heavy — of making greater contributions to the unpaid care economy and lack of access to crucial healthcare.

How did we get this way?

What happened to America’s middle class, which rose triumphantly in the post-World War II years, buoyed by the GI bill, the victories of labor unions, and programs that gave the great mass of workers and their families health and pension benefits that provided security?

Around 1970, the productivity of workers began to get divided from their wages. Corporate attorney and later Supreme Court Justice Lewis Powell galvanized the business community to lobby vigorously for its interests. Johnson’s War on Poverty was replaced by Nixon’s War on Drugs, which sectioned off many members of the low-wage sector, disproportionately black, into prisons. Politicians increasingly influenced by the FTE sector turned from public-spirited universalism to free-market individualism. As money-driven politics accelerated (a phenomenon explained by the Investment Theory of Politics, as Temin explains), leaders of the FTE sector became increasingly emboldened to ignore the needs of members of the low-wage sector, or even to actively work against them.

 Temin notes that “the desire to preserve the inferior status of blacks has motivated policies against all members of the low-wage sector.”

What can we do?

We’ve been digging ourselves into a hole for over forty years, but Temin says that we know how to stop digging.

If we spent more on domestic rather than military activities, then the middle class would not vanish as quickly. 

The effects of technological change and globalization could be altered by political actions. 

We could restore and expand education, shifting resources from policies like mass incarceration to improving the human and social capital of all Americans. 

We could upgrade infrastructure, forgive mortgage and educational debt in the low-wage sector,

 reject the notion that private entities should replace democratic government in directing society, and

 focus on embracing an integrated American population. 

We could tax not only the income of the rich, but also their capital.


 We have a structure that predetermines winners and losers. We are not getting the benefits of all the people who could contribute to the growth of the economy, to advances in medicine or science which could improve the quality of life for everyone — including some of the rich people.”

Along with Thomas Piketty, whose Capital in the Twenty-First Century examines historical and modern inequality, Temin’s book has provided a giant red flag, illustrating a trajectory that will continue to accelerate as long as the 20 percent in the FTE sector are permitted to operate a country within America’s borders solely for themselves at the expense of the majority. 

Without a robust middle class, America is not only reverting to developing-country status, it is increasingly ripe for serious social turmoil that has not been seen in generations.

In Other Words Revolution

Capitalism’s bad

I really hope i don’t see any fellow white Americans on this post talking about how we don’t deserve this because we’re “the greatest country in the world” or how “this shouldn’t be happening in America of all places”. It shouldn’t be happening ANYWHERE, it doesn’t need to be happening anymore, and the fact that it was already happening in predominantly nonwhite countries is largely the fault of white supremacy
