Answer:
Interest is always a bad thing.
Step-by-step explanation:
We could say that interest is the cost of using someone else's money. When you borrow money from a lender or depositor, you pay them an additional amount of money called interest. Accordingly, when you lend or deposit funds in bank accounts, you can earn interest. This amount is usually paid annually (once per year), but it can be calculated for periods that are longer or shorter than one year.
It's true interest can be a bad thing in some cases, but not all, since you can actually earn money yourself, and owing any kind of money makes you its slave.
