At present, neither party advocates the tax code so elegant it can reduce inequality, mitigate poverty, stimulate productivity, prevent asset price bubbles, stem community-shredding gentrification and drain the distended Wall Street cabal of its ill-gotten gains – in just one tax.
Land value. If we want a real overhaul/simplification of the tax code, the way to do it is to tax land value. It might be the only tax we need. No sales tax. No income tax. No payroll tax to fill a Social Security trust fund. No corporate income tax that, as we can plainly see, offshores profits. No need to tax labor and industry at all. Just tax the stuff that humans had nothing to do with creating, and therefore have no basis to claim ownership over at all. You’ll find that almost all of it is “owned” by the fabled 1 percent.
