I deny your major.
Would you apply this standard to voting? Hey, just a low poll tax, where’s the harm?
How about freedom of movement? Set up a toll system, so pedestrians have to pay a penny per block of movement.
How about low tuition for public high school? Or elementary school? Or kindergarten?
No, this is a silly idea, at least for education.
We already have low co-pays for some Medicaid services. But a person with low income or no income may hate paying even a co-pay of $1.50. Things like flu shots are gratis, and should be.
For university? Society’s need for educated persons is greater than students’ overall desire to be educated at their own expense; and greater than the demand the market will have for them after they graduate. Most college grads will not become rich.
Nominal fees won’t allow under-performing students to pay their way in. If you cut the cost per student down to a nominal fee, you’re already mostly funding it from non-tuition sources, and you probably already have to start screening students in some other way.
High-performing students already get scholarships. Poor students can get grants. So tuition looks like a rip-off of mediocre middle-income students, who are not so high-performing as to get scholarships, not so poor as to get a full subsidy, and not so rich that they’d pay more in taxes in a tuition-free system.
