The point of marginal taxes is to make it acceptable to turn a reasonable profit, but taxes get more and more punitive as profits go up, and thusly price gouging isn't really worth the effort.

It still incentivizes making money but rather than taking those profits and grinding employees, suppliers and customers, you're incented to invest that money back into the business. You can still make millions or billions in revenue and make a reasonable profit, but instead of Galenm, senior leaders and laerger shareholders making bank, the profits go either to wages, facilities or (if you don't raise pay or invest) to the government.

This is, incidentally, how it all worked prior to 1980 or so, when we had a functioning social safety net.

Put it this way: if Weston is already a multibillionaire and still makes $300M/y in salary and comp, plus additional bonuses, then we're not taxing Loblaw enough. Could they raise prices? Sure, they could, but why, because they don't make enough billions yet?

Nuts to this idea of "if we tax them, they'll raise prices and/or leave". I've had enough of being blackmailed by billionaires. They need us to buy their stuff and back their wealth; we don't need them. If, eg, Loblaw wants to raise prices to maintain unreasonable post-tax profits, someone else can step in and do the same thing and charge less, and Galen can fuck off.
