No, the problem is you don't get it. First off: a person with bad credit who can't qualify for a credit card typically has bad credit and can't qualify for a credit card for a LONG TIME. More inquiries (without approval) make your credit worse not better, so the more times a poor person tries to apply for a card, the harder it becomes. After a while, people stop trying since they realize they're only digging their hole deeper.
It's not a lack of foresight or a lack of planning or any of the other typical garbage people like you (that's people who talk out their ass about situations they know nothing about) like to use to blame the poor for the situation they're in. Are there bad decisions? I'm sure there are. I know I'd be better off financially if I had made some better decisions in the past, but "getting a credit card ahead of time" is not one of them.
But anyway like I said this thread serves no real purpose other than to give people like you a platform to victim-shame the poor.
