It is no vice to arrange one’s affairs such that he pays as little in taxes as possible.
Everyone should investigate this. Stop paying for your future executioners.
Sure; I remember learning the difference between “tax avoidance” (completely legal) and “tax evasion” (which isn’t).
I’m also doing my bit (for personal finance reasons more than anything else, but it dovetails nicely with the larger scheme of things) where I’ve dramatically cut back my spending - no more eating out/fast food, making my own lunch for work, etc.
It is amazing the types of people I don’t rub elbows with anymore...
