That's tax evasion, which is illegal. I thought we were talking about tax avoidance, which is legal?
No one is defending tax evasion, just the same as no one is defending piracy. It's reassuring, though, to see that your analogous arguments don't make sense either.
There are schemes out there that claim to be legal, and offer savings of up to 85% of your "normal" tax bill.
I can't tell you how they work, but there are people selling these kinds of tax saving services, and there are people making full use of them.
Yes, some are borderline illegal, but some claim to be 100% legal.
Again, if you avoid (not evade for the purposes of argument) as much tax as possible, do you not forfeit your right to complain about services paid for by tax? Yes or no?
