Remember that sales taxes & value added taxes are regressive; they take a larger proportion of a poor person's income. Some VATs, like SCHIP's tobacco tax assessed at the wholesale level, are then subjected to sales tax at the retail level. Fuel taxes, too. 
Since we seem to be in agreement that corporate taxes are built into the price of their goods & services (like a VAT), then I can only assume that you're in favor of raising the tax burden of the poor
as you increase corporate taxes. 

One should ask, "Why are corporations keeping their profits overseas?" By keeping their tax burden down, they keep the cost of their goods&services down, making them competitive in the international marketplace.
