Correct, I was taking up an example, which is why I used the phrase "one might say". I didn't advocate a specific position (higher or lower taxes). I am completely detached; I don't participate in the political system in America (neither do I plan to ever) so I simply don't care.
I am not in disagreement with your thesis. The problem that bugs me is this presumption that the people are not cognizant of what is good for them. Maybe, the people do something for a reason which is of interest to them (but not the reason that someone else thinks is right for them). E.g. maybe, the people who sue McDonalds don't want their neighbor becoming rich while they are poor. This of course is not limited to the poor; this is a human thing. I would argue that it is not in Warren Buffett's self interest to vote for higher taxes; then again that is my opinion and is not necessarily the same as his. If you examined your decisions over a certain period of time, you will find that the reasons you do something are not necessarily in accordance with what society (or $person whom you think is smarter than you) does them for.
