You can go to different countries for having lower tax rates, in my experience it is never going to be less than 35 - 50% for the amount of money I make.
I am not sure how is it not fair to combine VAT + income tax to understand how much you are actually paying to the government. Goods I "choose" to buy includes: food and clothing, I am not sure how much it is a choice or just a necessity. Buying a flashy car is a choice, buying bread or a medicine is not so much.
That's why I added the "(mostly)"; where I live, most food is exempt from VAT, which is as it should be. I agree that clothing is a necessity, so should also be exempt, but only up to a reasonable limit - and then things get a bit too complicated.
VAT is definitely a problematic tax because it tends to hit the poorer harder, but that doesn't affect the fact that it would be possible to pay almost none of your income as VAT, or you could pay millions in VAT; it's very different from actual income tax.
