I'm rather uncomfortable with a marginal tax rate above 50% though. Psychologically, there's something significant about giving the government a greater share of your earnings than you get to keep yourself.
And even tax rates of 50% should not be approached until we get really really high incomes. At least 1 million USD, probably more like 10 million. For people who only make 250k a year, even a 35% tax rate is a major burden that significantly impacts their economic decisions. For example, should I become a doctor or not? A 35% tax rate at the 250k level is sufficient to have a major chilling effect on people's willingness to attend medical school. This is in large part the same reasoning for why investments should receive a lower tax rate than work.
