>"Taxes are high so I won't try to make more money" - No one ever.

No, but the Swiss banking system, Panama Papers, Canadian shadow company situation et al. can attest to the fact that when income / wealth rises to a certain level and those who've earned / attained it feel the level of tax being levied at them is of an unfair level, a vast amount of money that could be taxed will be off-shored.

Everyone, particularly those in areas with a low sense of shared identity and the mutual obligations that comes with it, will try to minimize their tax bill some way or another and once one attains a certain level they will unlock mechanisms to avoid tax at a level that will be detrimental to the rest of the players in their given system.

There are lots of people who don't try to make more money because of roadblocks put in by the government. Obviously the uber-rich like Mark Zuckerberg or Bill Gates don't care that much about taxes but for someone in the low to middle income brackets it can be challenging to move up as you pay more in taxes and receive less help from the government.

If you make enough money that you can live comfortably and you would have to move up a lot to counter the offset to make more money in the next tax bracket, I think the majority of people would not bother. Outside of HN, a lot of people are satisfied with making an okay salary and having steep tax bracket changes just amplifies that. Obviously, everyone would like to make more money if they could do so easily but if it is very difficult to do so, a lot of people will not be bothered.

The people who do want to make a lot of money and become rich, well if they have to deal with crazy taxes, they are going to either find away around the tax laws, or simply leave the country which both options are not good for the country.
