This high tax rate is one reason why U.S. firms have stashed billions of dollars overseas and are unwilling to repatriate them home. As long as the funds stay abroad they are able to escape the high taxes. High tax rates not only prevent the repatriation of cash from overseas, but also the productive use of all that cash. For example, funds could be invested here creating jobs and potentially higher wages offered to workers.
