The idea is simple. Everyone has taxes taken out of there paychecks. Some President signed those taxes into law. The idea here is that the President who signed it into law take credit for the deduction with their name right next to item being deducted. For Example only:
Fed Med/EE/tip (POTUS) 384.33
Fed Withholdng (POTUS) 122.00
FedMED/EE (Obama) 39.22
FedOASDI/EE(J.Doe) 21.61
By crediting who signed the taxes into law, workers can be reminded periodically just who they can thank for it. This idea may discourage future Presidents from creating new taxes and give a lasting legacy to those that did.
