You are right if it's only a single business failing. However, even JPM or BofA won't survive if >25% of their customer deposits are withdrawn in a matter of days, let alone other smaller banks.
If 100% of businesses in a certain sector are a "failure" according to your definition, then I suggest your definition is wrong.
