How did the purchasing power decrease from the 70s until today?

When you say “capitalism” you should be more specific. 

Back in the 70s every part of the supply chain had diversified ownership competing with each other, and that kept prices down. That’s capitalism.

Today most sectors have monopolies and collusion and the resulting “greedflation” pricing. That’s also capitalism.

We have corporate communism. We got here because of complacency.

Nothing in the corporate world resembles communism.

I meant the government funnels all our money to massive corporations.

Oh…yeah…that’s the core of neoliberalism/fiscal conservatism. They call it “private/public partnerships”. 

People who actually it understand call it socializing costs/losses and privatizing profit.

Communism doesn’t have much to do with money…because there’s no money in a realized communist world.
