It's funny how people complain about paying these "unfair" taxes. You are in a position of wealth because of society and the services it provides, the more wealth you have been lucky enough to get distributed your way the more you help out with paying back - quite logical really. And it's not like you get a higher tax on ALL your earnings, just on that extra part over the limit.
For the people who go part time to not pay taxes, if you're only in it for the money, I hope I don't end up next to you in the cockpit.
