American corporations have been running a con job for years. They declare to their stockholders and their CEOs that they've made huge profits, and then distribute billions of those profits to those same shareholders and CEOs. Then they turn around and tell the IRS that they didn't make any money at all, it was a really bad year, and they therefore don't have to to pay any taxes.
The largest percentage of major corporations in America to pay no taxes whatsoever happened last year as a result of the GOP tax scam.
Elizabeth Warren has A solution to the problem: pay 7% tax on all profits that corporations declare publicly to their stockholders and CEOs. It's a small start, but an important one.
