The president that understood how high marginal taxes decrease government revenues was Ronald Reagan. President Reagan actually had a college degress in Economics. The Presidents John F. Kennedy, Reagan and George W. Bush when they cut marginal tax taxes ALL saw national income increase. Under Reagon, national income doubled, however, the Democrats that were ruling Congress at that time, tripled government spending, Hence the national debt and the deficit increased. Did the national media blame the Democrats for excessive spending, NO, they lied and blamed Reagon's tax cuts instead.
