This is a really interesting suggestion and makes a lot of sense.
I do think you may be under-estimating the faculty cost on business/econ/law classes, specifically. Faculty in those disciplines tend to be relatively well-paid[0] to compete with lucrative alternative careers as leading lawyers/consultants/financiers.
Using UVA Law as an example because I found numbers quickly... avg faculty salary was $180k in ~2013 (so say, $200k today adjusting for inflation)[1]. Faculty-student ratio is 6.2:1 [2]. That's $32k/yr/student in direct faculty salary costs before paying for employee benefits, administration, facilities, etc. Against that backdrop, ~$65k/yr/student tuition [3] seems pretty reasonable.
In Sweden, where taxes pay tuition, it costs about $4500 per year to educate a student in humanities and twice that in STEM. The salaries are of course lower though.
