If we increase corporate taxes, companies will respond by either raising prices, struggling to innovate/grow, or going out of business. Which of those outcomes do you prefer and why?
Corporations will continue to exist as long as there's a profit to be made. If they have to pay 10% of those profits in taxes or 80% they're still making money and there's still a profit incentive.
The idea that a tax on profits will drive a company out of business belies a fundamental misunderstanding at best or deliberate deception at worst.
Why would anyone invest money in that venture?
