Are you saying now that US taxes aren't too high after all, or are you avoiding the point that if you want the best, why wouldn't you expect to pay extra for it? ;-)

If you're worried about distortions, tax isn't the worst IMHO. The modern market allocates more $ to bankers than scientists and more creativity to marketing than to product. Apart from creating horrid nouveau riche, these behaviors stifle the sorts of innovation that until recently delivered most of the improved QOL at little extra cost. More and more $ is flowing to people who don't actually improve things for anybody except themselves. Why is that a good idea?
