"Also realize that companies also pay state income tax, state and local property taxes, numerous and increasing: licenses, permits, use fees, workmen compensation, unemployment taxes, regulation costs, etc. etc."
And yet somehow, after all of that, they manage to scrape enough together to pay their execs 7 and 8 figure salaries/bonuses/stock options, buy back stock to pump up the price to keep their shareholders happy and their own option lucrative, pay dividends, and fund lobbyist and political campaigns. And if they move their operations overseas? Why they get all the bennies you mention to boot. Never mind the economic devastation they leave in their wake. Hey, we can just retrain the unemployed for the high tech jobs of the future. But training programs cost money, and that means taxes, and besides most of those high tech jobs can be done cheaper guess where?. Why overseas, of course.
