Everybody loses. Think of all the students with borderline college potential and/or interest who will start "free" college. A lot of them would be more sensibly directed toward a trade or apprenticeship in manufacturing. Or to become assistants who can earn a living salary with a one or two year program, perhaps even manager training at a store or restaurant.
We all lose out if these people don't get trained for those fields. And they lose out if they start four-year college, but don't finish.....they'll have to pay it back.
