The US is progressive when it comes to income tax, but if you consider all contributions to tax revenue the US is basically a flat tax system. At least that's what the book Triumph of Injustice led me to believe. Like Warren Buffett literally said: “The wealthy are definitely undertaxed relative to the general population." And if someone has a billion dollars or more in unrealized wealth, forcing them to realize some of that wealth in order to pay taxes on it does not bother me much.
