Apple, and dozens of other large companies have parked billions of profits billions in cash in banks and nations in ways that shield it from US taxes. The GOP from state level to DC are offering a cure for this, if we lower our tax rates those companies will ship the cash home and pay down our debt.
First, the GOP does not want the debt paid down, their criticism, their tactics, their cuts on social programs and environmental issues are all cemented to the debt. Fix that and they may have to fix the rest.
Second, say we lower taxes to 10%, corporate at 5%, tell me which of those companies would bring that money into the open and give away part of it? We cannot compete with a Zero income tax rate. Unless, no no no that would be crazy, not zero.
(OK I know oil and many others who do keep some of their money here already pay zero, even collect more support above the zero, a kind of reverse tax. This is not that, this issue is beyond that. One more thing, as Gump would say.)
