I think the way you create this is to make college education free and of good quality for prisoners. To get the general public to agree to this, education would have to become free for everyone, at any age.
Can't think of anything worse than making it free at this point, putting the tax payer on the hook for a disgusting and bloated system that has gotten fat from signing young people up for predatory loans at a vulnerable point in their life.
Only way I'd agree to free higher education would be if it could only be staffed by people who have actually held the jobs they're claiming to be educating you for. Nothing seems more absurd to me than paying someone thousands to prepare you for a job when that person themselves has never had a real job outside of the academia clique which is far removed from the real world.
