For the majority of the time there has been a Federal Income Tax, there have been top brackets in the 70% range. This was a burden begrudgingly borne by the wealthy for many generations. It funded the US leaving an agrarian lifestyle and becoming a superpower. Did a 70% top-tax bracket force any of the uber-high earners to stop earning money because they didn't want to give 70% to Uncle Sam? No, the super rich will always want more money/property/dividends/etc no matter how burdensome the tax bracket they fall in might be.
