Really not a very practical question since it would obviously depend on what is being returned. So it's basically a matter of ideological rigidity: would you be bothered if, despite being completely happy and having every want and need taken care of, you also knew that you were paying 100% taxes. Or, more realistically, if you were very happy, had most everything you wanted in life, but paid 80%, would you want to reduction in that figure to take a chance on being even happier.
In reality, I think most people would be quite disgruntled with even a modest tax rate (say, 15%) if they knew it was being embezzled and that no good was coming of it, but would be fine with a higher one (say 30%) if they knew it was providing useful things to them and quality of life to others.
