I love my universal healthcare and pensions and am happy to pay a good tax rate for that, but many people seem to assume that it's just OK for governments to tax, and tax, and then tax some more.
Also, a motivated person is going to find loopholes in the tax code. That is essentially the result of being able to structure your own affairs the way you want, unlike, say, an employee. Don't blame the person understanding the rules well -- he's playing by the book after all.
