Holy shit, I had to go back to her post about scarcity:
...we largely don't have scarcity of necessities. America can not only feed, cloth, and house everyone in the country, but it could physically take in several millions more and do the same. The reason we have scarcity is because some folks have decided that stratifying access to basic needs is a good idea for the human species because it props up a very few powerful people, who then go on to lie to us that we can all stack ourselves at the top of the pyramid too if we "work hard enough" and "follow our dreams" and all that fucking bullshit.

Wait, so she thinks that people just create an over abundance of goods and services because there exists a deliberate conspiracy to inflate the value of them instead of scarcity playing out...?

So an oppressive system maintained for the benefit of a few operators at the top exists to change the market value of items and services in overabundance? And not one of those operators is trying to undercut the other operator in the system in order to profit off of it even more? Wtf, what is stopping someone from being part of the oppressive capitalist in that system? Why not skip the middle man and start selling clothes and food since they have no real market value? It's the capitalists setting the prices since there's no scarcity? WTF, you idiot - you work minimum wage. Go do it! You're one of the few people on earth, apparently privy to knowledge that will allow you to do whatever you want with your time because value isn't implicated in scarcity. You could just be a capitalist and take all of the clothes and food and resell them to people that don't need or want it.

The pyramid is very close because, as you say, scarcity and efficient markets don't exist. Step 1.) Buy item from idiot Step 2.) Sell item to idiot. Step 3.) Profit
