You can't demand systemic change, greater distribution of wealth and the liberation of workers from the ownership class if you have a house. If you have a house then those things are not possible. Having a house invalidates your participation in a society and any critiques of the economy.
The reason the soviets lost is because they had houses. Having a house is active participation in capitalism. Houses did not exist before and they will not exist after. So the only reasonable way to be a socialist is to sell your house. Then make a little house out of the money and sell that. All the way down until you have nothing left and then you will be halfway on your way to being a socialist but not until you sell your phone.. let me explain.
they're trying to make themselves feel better about choosing to be selfish and greedy
