anyway sometimes people do not have a choice because maybe they have a family that they have to sustain so either way they still need to spend more than they own which is why they tend to look for another source of income
No common sense at all (at least when it comes to "common") because most people have mortgages, get loans, or at least have credit cards, which means that they spend more than what they own.
Some people like living this way, and some of them will even explain passionately how credit can help you make true dreams that wouldn't be possible otherwise. But I'm one of those who prefer to owe as less as possible, and save for the future.
