What I've heard is "if you owe $1 million, you have a problem. If you owe $1 billion, the bank has a problem. If you owe $1 trillion, the government has a problem"

If everyone owes the banker £1M, it's the insurer's problem.

Then the government's problem when the insurer melts down.

And if something is everyone's problem, we just ignore it.

It's so efficient.
