jack has a creadit card. a person who can apply for a credit card is an adult who is old enough and wise enough to manage his/her own money, jack spends for gas expenses,clothing,food,and other living expenses by paying with his credit card means he is still not wise enough to maintain his money management, because jack doesn't have the ability to choose which expense is more important.
everytime we spend money by paying with credit card , we have to pay an additional fee to the bank.if we cant't pay it all in 30 days,the additional fee will keep increase.so,including to my opinion,people who can't manage their own money like jack are better to not own a credit card before they broke them selves by spending more than what they earn in a month.
