If the public benefits of a physics degree exceed those of a women's studies degree then the former should be subsidized but not the latter? What if the former's benefit exceeds the latter's benefit by an epsilon amount? By your reasoning only the most beneficial degree should be subsidized but not any others. Perhaps you typed in haste and did not mean what you wrote in a strict sense.

I don't believe one can really quantize which degree has more public benefits. Some benefits are hidden, in the sense that their benefit isn't so readily recognizable. The benefits of an educated populace are manifest and, I believe, clearly worth the expense of public financial support.

To be more precise, what I meant is that both should only be subsidize to whatever degree they create external benefits. I.e., if a physics degree has $5k external benefit and a women's studies degree $5, then the physics degree deserves 1000x more subsidies.

And once you factor in the harms caused by signalling, it's far from clear it's even a net positive.

The benefits of an educated populace are manifest and, I believe, clearly worth the expense of public financial support.

The external benefits are far from clear.

If a person is educated and becomes a doctor, and then fixes my spine in return for money, the benefit is clear. But that benefit is fully captured by myself and the doctor, and he factored the cost of education into the price he charged me.

Can you name what the external benefit (i.e. benefits captured by third parties) is, for both medical education, physics education and women's studies?

The external benefits are quite clear to me. That they are not clear to you suggests to me that nothing I write or say will change your mind. So what's the point of asking me to list them? Are you merely trying to see if I understand the concept of a external benefits or genuinely trying know what possible external benefit there could be with someone being provided a subsidized education? I think you can think of some.

I'm trying to know what external benefits you think exist and why you think they are uniform across all fields of study, which is a much stronger claim that you made. I cannot think of any such benefits.

E.g., one might hypothesize that people in college develop useful skills that benefit others in a manner they cannot capture as wages. But it's a little crazy to suggest that a women's studies major develops those skills to the same degree as a nurse.

I've not made any claims of uniformity. I've not suggested such a thing.
