There aren't many options for fighting the tax man, "In this world nothing can be said to be certain, except death and taxes". You're only option is to leave the US for somewhere better.
Maybe an American can chime in here on this...
I think the root problem with how the US currently spends its tax dollars is the above "vote with your wallet" belief in the first place. "Vote with your wallet" implies that the rich deserve more votes. That's not (representative) democracy, that is oligarchy. Right now the US has two political parties that are both "vote with your wallet parties". They both act like they are bake sales that constantly need everyone's $20 bills just to "survive", but as much as anything they are trying to make US citizens complicit in agreeing that the rich deserve more votes and should control more US policy.
I think the only real solution to a lot of US ills is drastic Campaign Finance Reform.
And, of course, in the ancient world, free citizens of Greece and Rome considered direct taxes tyrannical and usually avoided them, leaving such burdens to conquered populations.
So I guess taxes are uncertain, but only for the oligarchy.
