Explanation:
When a person rent's something then the same amount of money has to be paid monthly or the predetermined amount of time. A person may keep paying after the value of the thing is obtained. Then renting becomes a waste.
For example, you are renting a car you pay 1000 dollars every month. And the car costs 10000 dollars. So, the person will be able to buy the car after 10 months. If he rents the car for more than 10 months then he is paying more than the value of the car itself. Then renting is sometimes considered as “throwing money away”.
