It's a matter of principle. If a anyone only steals $100 it's "better" than if he stole $1000, or all your money.

It's why you'll thank a cop that lowers the charges for a ticket, even if you're a single mother that needs every dime to feed her kids.

So when you are taxed less, it's "better" for your situation, but the offense is the same. The fact that they claim a coercive right to your money means they set the amount, you're a victim just the same.

IMHO There is no moral difference.
