For a personal relationship, this is absolutely true. From a business perspective, this is extremely naive. Everything a business does is in the name of profit, and banks are no exception. They lend money with interest because that is how they make money.

No business is your friend, if you think otherwise, you're a sucker. They will do their best to keep you happy so you keep consuming their product, but 99% of the time they will never do something for you that doesn't benefit them.
