Your contention is that if my company didn't have to pay payroll tax then my salary would be 7.65% higher? Or that if corporate taxes are cut then business will pass the savings along to the consumers? Will all due respect, that's the craziest thing I've heard in a long time. A company's first duty it to their shareholders. THey will pay a person as little as they can get away with, and charge as much as they can get away with, and any savings anywhere along the line will go in their pocket and not in mine.
I guess you have never run a business. All it takes is one competitor to lower their prices in order to gain market share. The companies that don’t pass the savings on to their customers will find their sales dropping as they try to pocket their diminishing profits. Do you not compare prices when you shop?
