1. almost everything is capital gains (which comes to 23.6%). Note that this was 15% under GWBush, so it was even better back then.
2. You can avoid state taxes by relocating to WA/TX (If I recall correctly, this was Bezos' motivation for starting Amazon in Washington). A lot of billionaires live in 0% state capital gains tax states, except the ones that need to live in CA/NY for the tech/financial sector respectively. If you live in one of those, then think of the total taxes as more like 33% total (federal + state)

Effective tax rate plateaus at around a half mil in annual income, then starts going down again after around five million.
I couldn't find any hard data about brackets above that. Didn't Mitt Romney pay around 15%?
Then there's my all-time favorite quote, of Leona Helmsley:
>Only the little people pay taxes.
But, that's only anecdotal, heh :-)
It's also worth noting that the tax rate for the very rich is still 15%. As far as I can tell, certain very rich people "not paying taxes" is a myth.
Finally, it's worth noting that Notch is not American.
Rich people do have ways of reducing their tax burden, sometimes to surprisingly low amounts.
[1] planning is normal reduction of tax burden and is unlikely to be challenged by tax authorities.
[2] avoidance is legal, but sometimes exploits loopholes in tax laws in weird ways and you might risk the Inland Revenue changing the regulations - sometimes retroactively.
[3] evasion is just illegally not paying tax.
Exactly, there are good reasons for this. The problem is that it would be grossly unfair to tax a small business owner or small investor at say income tax levels because their risks are so much higher. On the other hand a big investor will millions or billions ends up paying the same tax rate as that small business owner or investor, but is able to spread their risk across many investments reducing the overall risk. Yes it would be unfair to tax them at a higher rate for doing fundamentally the same thing - how would we justify one tax rate for one investor in a company, but another rate for this other investor?
Taxation is a hard problem.
Because taxation has gone way beyond what it was initially meant to do. That's why it's a hard problem; we're trying to make value and fairness judgements and using that as a basis for applying tax.
To me, personally, people can't claim fairness if they're treating people differently based on their arbitrary value judgements. Until we start treating "fairness" as a universal, with no subjective component.
The big reason why the rich guys can lower their tax rates is because they can use investment losses to offset taxes. It's not a loophole, just a tax deduction you can optimize.
