The phenomenon emphasizes the wisdom and need for real anti-trust law and enforcement. Sure, let these fuckers go out there and leverage to the hilt, and crash and burn. Just none of this "too big to fail" shit (which, when you let one or two entity's become that dominant, is an actual thing -- their failure could lead to total economy disaster). It is bad policy to (1) allow an enterprise to get that big/economically dominant, (2) gamble with its own life, (3) lose, and then (4) say "nope, you can't let us crash, we're too big and too important, use the people's money to bail us out." The thing is, item (4) is not untrue in many such cases. So....don't let it become true.
But, we have no interest in doing that. As a society, we live to serve monopolies and oligarchies, and you and I have no purpose other than to be a source of revenue for those things. That's fucking fucked. The economy should serve and benefit its citizens, not vice-versa.
