Just need to make corporate taxes similar to personal ones, but as a percentage basis. Did you have a 40% profit? Okay, you pay 37% in taxes on money earned above that. 35% profit? 33% tax.
Stock buybacks should be considered profit for tax purposes.
If an employee gets paid more than 50% in stock/stock options and the company has more than 10 million in revenue per year, the company should pay taxes on that as well.
If we did that and closed a few other loopholes, we’d probably see companies investing more into the business and prices would also not rise quickly.
