Banks tend to feed on other banks.

I've looked at the merger chains involved in the banking world.

It appears that the banking sector has a long history of collapsing in on itself.

The public does not notice it because banks (subsidized by the Feds) have a history of buying up the accounts and IP of the failed banks.

The public just sees the buildings and the brands and fail to notice that the ownership of the banks keep changing.
