When $1 Trillion is reintroduced into our local economy from repatriated monies without expanding the monetary supply, all bets are off. Having this money out of bounds is problematic. Yes, companies can lend it to themselves, but this is not a clean transaction, having overhead and waste to the US side.
This, coupled with a low business tax (and even lower repatriation tax) will be a beautiful thing to behold.
