Difference between the capitalism our parents had vs us. They had taxes on the rich. So they could afford homes and retire and never needed 3 jobs to scrape by. In fact one job was enough to afford a home and a family.
Taxing the rich is great but it's not gonna fix any of those.
If even the rich couldn't or didnt want to afford $5 quarter potatoes then they'd have to lower the price
If we took all the assets from all the billionaires in the US, that total is something like $6-7 trillion if we pretend there's no asset price decrease in the selling of said assets.
Sounds like a lot, but we're nearly $40 trillion in debt. Taxing the rich heavily won't solve a spending problem.
The federal government specifically, and the admin class in general was a lot smaller during our parents' era.
