I know gold is the long term investment to make, but I just don't understand why.

If things get bad enough that I need to utilize the gold, who is going to give me anything for it or who can afford to give me anything for it?

Maybe I'm being unwise and overly skeptical for not having any, but I just don't understand why gold would help me out when everyone else is not doing well either.

Am I missing something super simple?
