My understanding is that most (informed) people who complain about the rich not paying taxes in the U.S. are talking about capital gain taxes, inheritance/state taxes and other forms of money-from-money types of wealth. They might also be thinking of accounting tricks and deductions that severely reduce the actual tax paid for most people wealthy enough to hire the legal and accounting help required to get the most of tax laws and loopholes. Income/pay taxes in and of themselves are fairly progressive.
