“When a bank goes bust the FDIC only pays off on accounts where the owner/depositor has a social security number or a tax ID number.”
Don’t many illegals have TINs that they use to file for income tax refunds?

Happens every day.
The people I was pointing to usually do manual labor, live 20 to a house, and don't know about TINs, and probably aren't literate.
