The big banks total make $12B/profits.
From exorbitant, punitive, and often"backdated/frontloaded" processing, overdraft charges, they make $38B/year.
Without overdraft penalties, they're bankrupt.
The financial reform bill limited some of these fees, rates, penalties, but on consumer cards only.
To escape/gut the financial reform limits, the cc issuers have shipped out millions of non-solicited, non-regulated business cc's to consumers.
Paranoia is when you imagine threats and dangers that don't exist. It's not paranoia when you think the financial sector is out to you hard.
