Anger at the banks

It's hard not to be irritated by banks these days.

It's hard not to feel outright anger.

Fixing interest rates, mis-selling products ... on top of the crisis they caused by the way they acted before the credit crunch and recession.

And they still merrily charge individuals and business owners punitive amounts when they go ever-so slightly overdrawn. Yes, it did happen to my business recently. Overdrawn for less than a day: charge of £30.

How is this justifiable?
How does this help?

If my business was really short of cash (it's not - it was just in a different account), how would charging the business help that cash shortage?

And yet banks are supposed to helping businesses.

The only business they're helping is their own. Helping themsleves to our money.
