When I was reading sites on credit card debt and in forums for CC and such, that is NOT exaggerated based on everything I read on the forums.
People posted saying they can't figure out how to unbury themselves from debt and people responded with they can help if they lay everything out for them. Well, the people needing help do just that and they list their $50k in credit cards they can't get out from under, then list their dual $90-120k incomes, the BMW, Mercedes, and new truck, the $800/month private violin lessons, the $1000/month for private school, along with all the frivolous spending like exactly that, the several hundreds a month for new clothing. It is definitely out there coming from the real people on discussion forums just like this and not coming from Hollywood television programs.
People at the poverty level are not spending money like that, though. They don't even have credit cards. They mostly don't even have bank accounts.
