If my business had unending customers, I would be rich. More customers, more sales, more profit.
Hospitals are constantly flowing in visitors. How is it that so many keep going out of business?
Illegal alien criminals get their hospital services for free. The rest of us have to pay, but can't afford it. Hospitals provide free services to criminals, those who can't afford the bills don't go, so no profit on NO sales .. simple business logic.
Customers means people who PAY for goods/services. There are only a few of those left.
