Very large companies are keeping a lot of money overseas. It seems be very inefficient if their saving are not used in investments that are closely connected to consumer financial benefits. Should society be concerned with the flow of money out of the local economy? Isn't it a idea (for the companies) to move hundreds of billion dollars out of the economy their customers need to make a living? I wonder if these companies should offer low interests loans to people to buy their products in much the same way that China buys US treasury bonds. Maybe there should be limits to how much a company should be allowed to save and it should return the rest to investors.
