A huge amount because and raise changes every ROI calculation. You can look back in history and see that the wealthy move their assets to tax-free shelters as tax rates rise. Take two companies A and B, under two different tax rates 10% and 90% respectively. For an investor to earn the same return company B would have to be 9x as profitable as company A (made simplifying assumptions). That's why increasing tax rates hurts, it makes competitive investments next to impossible to find, so investors shelter their money instead slowing growth, job creation, and wealth creation. The extents that I have gone to to limit my tax liabilities in the past are ridiculous. To think how much time and money I have wasted that could have been put towards productive aims. It's sad.
