I think you'd be amazed at the number of Americans who'd be OK with that as long as the same rules were applied to everyone with similar financials. Yes, we have a large faction of this country who are destructively greedy, who care only about what's best for their personal, immediate bottom line. They are "glass is half-empty" sorts who obsess over the portion of "their" pay they don't get rather than the great wealth they do get. They'll fight tooth and nail to avoid paying even one extra dime of taxes, no matter how trivial the impact on them financially.
Others, however, are not driven solely by greed. They recognize that as much as their financial success may be due to their hard work and good decisions, it is also due to the bountiful opportunities offered by America's tremendous physical, financial, and educational infrastructure -- greatly funded by tax dollars. Therefore they are content to return some of that investment, to pay their dues, to celebrate their glass being not just half-full, but also orders of magnitude larger than it would be in those low-tax utopias (i.e., third-world hell holes) so many on the right seem to want America to become.
