How could consumer credit be a good thing? What down sides can consumer credit have?

The correct answer to this open question is the following.

Consumer credit could be a good thing because if you keep a good credit record, you won't have any problems with your bank, you will be able to ask for more loans, borrow more money to do the things you want to do and that credit will be on better terms for you. The relationship with the bank will be a healthy one.

On the other hand, the downsides that consumer credit can have is precisely the opposite of the above-mentioned ideas. If you have a credit and don't pay on time, you will be charged interests so you have to pay more. This bad credit record is a negative mark in your credit history and in the future, it will be more difficult for you to borrow money.
