The only reason this happened was due to taxpayers bailing out financial institutions. This only exacerbated an insane amount of moral hazard already present in the market following previous bailouts.

Unfortunately, the US Government continued to run themselves into the ground spending-wise and may have a difficult time with another bailout, unless everyone pretty much agrees that we cannot have a USG failure, so they all pretend like nothing happened.

Eventually the merry-go-round stops, I'm just not sure what the catalyst will be, and it might be 100 years from now.
