Really ? Perhaps you want to consider Spain. They have stable but higher corporate taxes then neighboring countries. So, not being stupid, corporations simply are shifting their profits and operations to these neighboring countries. Spain's income from corporations is plummeting.
The truth is that the "rich" and corporations are smart enought to move their assets to locations where they pay the least amount possible. It's about time the US became such a place. Once we do, you will find that tax revenue from said "rich" and corporations will increase.
