What drove business off shore was high taxes and regulations they couldn’t compete many congressmen received a hefty kick back.

The drove GM Ford and Chrysler out of Los Angeles years ago in Detroit now with pay and perks they make well over $50.00 per hour.
Everything has limits got to know where they are.
All of those extra costs, pennies on the dollar to the consumer buying the products, was passed on to the consumer. The consumer paid for those taxes and regulations. So your supposition is wrong. Nothing "drove" them offshore but pure greed, corruption and globalism. The workers paid the ultimate price for increased profit margins with lost jobs, lost wages and destroyed communities. F all Free Traitors. F the all.
