It's a no-brainer, alright.
Take two companies making similar products. Say, Apple and IBM. Apple decides to move overseas, pays lower wages and enjoys lower shipping costs as a larger portion of their customers are closer (Chinese, Indians, Pakistanis, etc). IBM decides to remain in the US. A few years pass and Apple wants to bring that money back to the US.
Now let's say both Apple and IBM are working on developing a new computer that will be able to detect the real time demand on the local power company. Home owners will be able to purchase this new product and will be able to see the peak periods. People using electricity during that period would be charged a higher rate so they would avoid using things like the clothes dryer, hot water for showers, etc. until the peak subsided. This invention would generate vast profits for whichever company invented it. Apple, by not having paid the same taxes as IBM paid towards social benefits will have more money to invest in R&D and will have an unfair advantage.
Obviously, IBM and every other company will follow Apple's example. Fire employees, close plants, stop paying taxes towards US social policies and move overseas. When an opportunity arises to develop a product that is geared to the US market move the funds back to the US and outspend other companies that remained here and contributed to society.
Is that what you want to see happen?
