Tax Foundation info is based on federal tax returns and calculated on AGI. Regardless of how it's sliced, diced, mangled, mauled, or masticated, it still stands that the top 50% of wage earners pay essentially all taxes on personal income.
Property taxes are a different discussion, but given "the poor" get huge income tax breaks on a significant portion of their income, get the advantage of "free stuff" programs the rest of us can't touch, and have a much higher ratio of housing subsidies regardless of ownership status or property tax assessment, my sympathies are somewhat subdued.
Finally, those "most wealthy who collect low or no income" don't just bury their money in a hole. They invest it, they buy things, they employ people, they take venture capital risks... all of which plows money back into parts of the economy both heavily taxed and solidly beneficial to "the poor" and middle class. Taxation-equivalent expenditure isn't avoided, it's just shifted from straight taxation into other financial instruments.
