Aren't you presuming that humanities have humanity and STEM/business graduates are somehow less moral? I suspect there is an insidious presumption behind your comment. Some discussion here:
https://news.ycombinator.com/item?id=37097655One effective but evil engineer in power could do a lot of damage. Hitler wanted to be an artist but couldn't get into university. Although if I'm going to use selection bias: some of our tech overlords seem morally repugnant.
I wonder if we could show that:
(1) humanities graduates have better morals, and
(2) that those graduates got those morals by going to university (versus had them as children - selection bias of those choosing to do humanities).

Can of worms: how to successfully teach people to be ethical. Certainly our churches seem to me to often fail: fail at the level of the individual (I have met enough arsehole Christians), and fail at the level of a society (a group of Christians deciding to do extremely unchristian things).
