Answer:
free rider
Step-by-step explanation:
In economics, free riders are considered a type of market failure, because they use a product or service without paying for it. This results in higher costs to those who actually pay for the services or the goods. For example, a person that lives in the suburbs and commutes to work every day to a large city. That person doesn't pay city taxes, but benefits from all the free or subsidized services that the city government and other organizations provide like roads and sidewalks, subway or buses, police and other emergency personnel, parks, etc.
