The bank through it's history has returned more to the treasury than it has taken. It is one of the very few government programs that have a demonstrable positive effect. It serves a legitimate purpose and not having it available puts American companies at a disadvantage. It will force larger companies to continue to move their operations offshore, which will result in even lower corporate tax revenues, which will result in a move by the political class to raise corporate tax rates, which will drive more business offshore. Destroying commerce for ideological purposes is not a good idea.
