Labor tax (income tax) is outrageous. It's a form of slavery. As has been stated here already the income tax always falls on the middle class and poor to pay it. Wealthy people evade it, either illegally or legally by passing laws that make their evasion legal.
This is true everywhere. For instance in Britain they have tough tax laws, but there is very little compliance among wealthy taxpayers. In the US there is more compliance, but the laws are structured so that wealthy people end up paying very little.
More legitimate forms of taxation are resource consumption taxes and true wealth taxes that only affect unquestionably financially secure people, say with net worths of over $5 million.
Financial security is an interesting thing. Why does the government aggressively desecuritize the middle class and then offer them paltry concessions in return like Social Security and Medicare? Government should actively work to securitize the middle class, and the first way to start is by not stealing their money from them.
It's better to have independently financially secure people than a population that is taxed dry and then given government "services" that most people would pay to avoid.
