Re: VAT
No, because I value morality above profit.
So you voluntarily hand over more tax than you are legally required to, every year? That's nice of you, but perhaps you'd consider giving to some charities instead, they'll likely use it more wisely.
Avoiding paying tax that you don't legally have to is entirely reasonable. Evading tax that you're legally required to pay is of course both morally reprehensible and criminal. Not the same thing.
