That's nice to hear. I'm nowhere near the upper tax brackets at the moment, but I like to think that I would be okay (and even encouraging) of the taxes I did face in such a situation.
I know many people who make lots of money and are bitter about paying so much tax on it, but very few people who realize that the taxes they pay make a real difference in everyone's lives (especially the lives of those who are less fortunate). Or that the taxes they pay make possible all of the benefits the Federal, State, and local governments offer.
Sure, the government may not be the most efficient of entities, but I think it's difficult to make a serious argument that we would be better off without most of the services provided by the various levels of governments, or that they could easily be replaced. And none of these would be possible without some form of taxation (though how the taxes should be structured is up for reasonable debate).
While I believe that people should be fairly compensated for their hard work, and that we shouldn't penalize people for working harder, I also believe that it would benefit most people to stop and think about how much their taxes help to make this/any country a great place.
*disclaimer: this is mostly about the US, as this is my main experience, but I'd guess most of it applies to (at least some) other nations as well.
