Not that I disagree with the idea that you should reduce tax where you can, at least from a purely personal POV, but there are plenty of dumber things to squander your earnings than to pay taxes.
Alcohol and drugs, buying a new car when you already have one, buying a big petrol-guzzling truck when the only heavy lifting you do is pick up the groceries, buying a big rifle for your protection only to lock it behind a safe that you won't be able to access quickly enough in an actual situation that calls for it, etc.
Purely from a PR side of things, it's difficult to claim to be a patriot when you pay your taxes to another country's government.
