What you have just described is people wanting investment in common society - you see the return on this investment but ultra-capitalistic individuals don't see any returns on this investment because it doesn't benefit them.

In other words, you just asked for higher taxes on the rich that your elected officials could use for your desired investment. And the rich don't want that which is why they spend on lobbying.
