Years ago when this trickle down theory first became a GOP mantra, it was supposed to lead to more prosperity for everyone. (So we were told) Theoretically, unfettered by tax burdens, if businesses had more money they'd invest it back into the business and create more jobs. Instead, it turned out just as some of us predicted. Only pennies on the dollar ever managed to trickle down to anyone. Instead it found it's way into the pockets of the CEOs, their boards and their stockholders.
Worse, they used the money to buy our government.
