Corporate Taxes

What is this insanity about corporate taxes?  Why is it the liberal Democrats always want to levy taxes on the big "greedy" corporations?  Anyone with an iota of intelligence knows corporations don't pay taxes.  They may write a check to the government, but then they simply pass the cost of taxation along in the price of their product to their customers.  That's you and me, the ultimate consumer.  We pay ALL the taxes.  The Democrats talk (rant) about giving the working class a tax break by taxing corporations. Its a sham.  They're either ignorant about things economic, or they are fostering a ruse on the unsuspecting uninformed "working class."  Are we crazy or what?
