Government ? Government of the people, by the Corporation, for the Corporation ... or to put it a different way ... to ensure power for those in the upper echelons of the big companies to earn more money than they can use in a lifetime. One can't really even say it's for the shareholders since so many companies pay no or small dividends. The money being made in the markets is a loss for others, just like playing poker ... The winner gets the money the others at the table lose. For every winner, there are lots of losers.
This kind of tax is just the arm of the greedy in corporations reaching their grubby fingers out to earn more money via government instead of raising their own bills.
We are owned by corporations. We don't own the corporations. Our governments are owned by the corporations ... we have next to no say in our government.
