I'm fortunate enough to be fairly wealthy (not gonna mention numbers, but I'm over the 250k/year thing), and I really don't mind paying more in taxes at all.
I'm probably the only wealthy person in the world who will say that 
But I know how hard it is for many families to survive on a very limited income. I've been there. I have many friends who've been there and/or are still there. Hell I grew up in that kind of environment...there was no silver spoon in my mouth growing up.
There are TONS of excellent, excellent people who work hard every day (many harder than myself I'm sure), yet can barely support their kids. And yet here I am, after a series of fortunate events, sitting comfortably. How is that fair? I just as easily could be in their shoes too if things hadn't gone my way.
Anyway, I don't want to write an essay, but I really feel wealthy people who habitually whine about taxes are simply greedy. You don't need a 8000 square foot home, 5 hot sports cars, a yacht, a private jet, or whatever else. How about lending some extra support to the country that enabled you to live such a wonderful life to begin with???
