Tax evasion is illegally trying to avoid taxes. Tax avoidance is making use of legal loopholes to legally not have to pay any taxes. Those companies and billionaires that are responsible for the greatest wealth inequality in the world, they are not amassing that wealth illegally, they make sure the system won’t come after them, either through tax advisors or through tax lobbyists. Usually “tax evaders” are the people who manage to get rich without the experience or the con men who don’t know when to stop like Trump.
