Lions and tigers and tax bears, oh my! Much of the discussion above evinces extreme and perhaps willful ignorance about the way the tax code actually works.
Due to the nature of my business, I have to pay taxes in about 26 different countries. And let me tell you, things are tough all over. Should I be angry about paying for an Autobahn I have never driven on?
The reason we have relatively high tax rates on worked-for income in the U.S. is because we have lots and lots of exceptions for very special people who do very special things, and maybe some not so special, but still quite creative. So the real trick is to do as many of those special things as possible so you qualify for lower tax rates. For instance, the average worker can only put $17K per year in an employer-sponsered 401(k). Structure things right and you can goose that up to about $100K or maybe more. Also, moving income outside the U.S. can work wonders if you put it in the right place. If you are good at playing the game, you can probably get yours down to between 10-15%, no matter how much you make.
Honestly, if you are ERE, you should be paying very little, because you would have very little earned income. All the more reason to get there sooner rather than later. Here's a real world example:

When we get rid of the exceptions, we can have lower base rates. Until then, if you are paying 50%-plus, you probably are not playing the game right. Or need to talk to a tax accountant. I can't say I have much sympathy for people who choose to remain ignorant of their potential options.
The alternative solution is very simple -- just move somewhere where the taxes are low or non-existent. It will be underdeveloped, but you can build your own compound and live in relative security from the tax man. For example, Doug Casey touts moving to Argentina. If you expect to live in the relative comforts of modern societies, expect to pay for it.
