I don't know why you have these kinds of thoughts. you may even have bad experiences related to those things. Well, I will give my thought also here, but only on some points:
Dont pay taxes
Taxes from the government in a country is a must and there will be some punishment if we do not pay for taxes. Well, as you say, we may be rich if we do not pay for taxes, ut, our life will not be calm and we must be chased by the authorized party and get punishment. Personally, I will prefer to pay for taxes and live well and calmly without worrying about the problems.
Evading tax is an offence but we can avoid tax paying like how warren Buffet did that, Tax is for the middle class and salaried people because rich people knows how to avoid them.
