Just because US banking sector is a fragmented mess doesn't mean that rest of the world has the same.
I'll say. A few years ago I noticed in the news that my bank's system had been broken into and sensitive information was accessed. And of course my bank didn't bother notifying me. A couple of days later I'm trying to check out at the grocery store and my card gets rejected.
I get home and find my account cleaned out because of a charge for over $1,500 to some jewelry store in Thailand. The bank returned the money, but if I didn't have other means available, I'd have been hungry for a while.
