Standardize arbitrary credit card cutoff times until 12:00 .a.m./midnight in the time zone in which the card is registered so there are no more ill-gotten gains by credit issuers; and, so that any such monies will now go toward stimulating the economy as opposed to fattening already plump corporate balance sheets.
Why is this important?
Credit issuers have arbitrarily set cutoff times on one's payment due date that can result in much ill-gotten revenue that might otherwise be stimulating the U.S. economy. For example, Citi Bank cuts off at 5:00 p.m. EST. I paid my bill on the due date but at 6:00 p.m. CST; and, as a result, I was charged a $20 late fee and $1.01 "interest". It's easy to forget that a particular card has an unusual cut off time, like that of a gas company who's cutoff time is 3:00 pm. PST.
