I just assume the government knows who I am and what I'm doing all the time, and just try not to do things that they might care so much about. Usually what they do care about involves massive amounts of untaxed money, so I'm pretty safe in that regard.
I have no qualms about paying my taxes, either. But then again I live in a very good country. Can't say the same of people living under the boot of a dictator like in NK
