Total USA household wealth is somewhere around $50T, GDP $15T. Per parent post, the bottom 60% has 4.2% of wealth: that's $2.1T, or average $11,150 per person - most of which is not "disposable" (tied up in home, car, and other nonliquid essentials). Assuming same distribution for income, that's averaging $3,343 - again, most of it not "disposable" (rent, gas, food).
Yes, there are a lot of them ("poor" still being a debatable moniker when you're making more than 15x income of half the people on the planet). A lot of money can be made there, and many manage to. To the point of the lead article, a little bit from a lot of people can add up nicely for a business. To your point, there are indeed a lot of people sitting on a cumulative lot of money. To the point of the post in between, eliciting a lot of tiny slices from a lot of small piles of money is a lot harder than eliciting the same sum from a few piles orders of magnitude bigger.
How about do something to uplift poor people, rather than just siphoning more money away. Affordable medical, dental, and legal help would be great focuses.
