It's a very tricky problem to solve at the individual company level. There are many things to consider and nothing prevents business from just spending more or moving money abroad to avoid taxes. If a business is big enough to have someone optimising their taxes, they're likely keeping only a proportion of profits in the USA based on how much they want to redistribute to the owners. In general, Corporate Tax Income is roughly 1-2% of Gross Domestic Product. Also, big business in the USA lobbies ~3bln per year - it's money going from business to the government, albeit I'd class it more as corruption than taxes. It's anyway much less than what you pay in %. As it's normal when you have a central corruptible government: whoever holds the more power will get the better treatment. If Amazon leaves the USA, tons of workers are going to become unemployed. If you leave the USA, it doesn't change much (especially because you'll keep on paying taxes until you renounce your citizenship).
