Perhaps a good question to ask would be is the US government corrupted enough already to assume that evading taxes became moral for normal citizens.
Sometimes it seems to me like conservative Russian entrepreneurs paradoxically behave *as if* they were anarchistic: they don't normally fairly pay taxes and the craziest ones may even openly declare that fact. They just want their weak businesses to survive, so everybody knows that and nobody touches them (unless they approach a particular income threshold that they constantly sense from culture). So they perceive the tax evasiveness as something moral rather than some form of protesting, even the most conservative ones; they know that government is more corrupt than them (and paradoxically precieve the government corruption as something healthy). Quite a sad situation.
At least Americans can currently *technically* protest their government corruption, including by evading the IRS right now. The paradigm needs to be changed though: it's not evading, it's protesting, boycotting to make corrupted system weaker in a hope to make a change. And I have no idea whether it's in any way effective.
