The only way cutting corporate taxes would ever help the working man/woman is if there was a stipulation that the total and exact amount saved by the employer/corporation from the previous year was required, by law, to go into increased wages for the employees.  Otherwise most employers will just rake in bigger profit margins.  Very few would actually put that money back into the business itself.  When the Greed Over People (GOP) talks about trickle down economics, it isn't income that trickles down to the common man.
