Problems by Credit cards.
I think that the Credit Cards creates long term problems for both the country and the world. It becomes a problem as credit cards provide money that you dont have yet which will build an unsafe sense of comfortabilty in the mind and can sometimes lead to overspending.
Credit cards can harm the stabilty of the economy when they create an unsafe sense of financial comfort in the mind. This unsafe sense of financial comfortability quite often lead to overspending, and when one can't pay up the outstanding.. it becomes a Problem. Banks must do a background check of a person financial status and also their spending behavior alongside with the capabilty of paying back.
