Globalization, and the ability for a business to cover such a large area of the world, is how that "Too big to fail" phrase came about.
Actually, the phrase "too big to fail" is a misnomer. When it's said, it's usually by politicians who really mean "too big to
be allowed to fail," and who are using that as an excuse to inject public money and regulation onto a company that would otherwise fail. It's the antithesis of a free market and globalization; it's government choosing who gets to win despite their bad economic decisions.
Companies are never too big to fail; anything can fail if it makes enough bad choices and unsustainable expenditures of resources. Even those companies propped up, mercantilist-style, by crony (so-called) "capitalism," will eventually fail when the government that decided they get to "win" runs out of money. That usually means a collapse of that government's finances, however, so really, everybody except the elite few skimming money off the transfer from earners to spenders is better off if we don't allow such shenanigans and instead allow companies that are failing to simply
fail. Then, people learn from their mistakes and do better next time to avoid the same fate.
