I'm glad you pointed this out because I think the difference is due to philosophy grads being ready and willing to enter the workforce as a welder or an au pair or a restaurant manager, whereas a CS grad is gonna hold out for a CS job.
Source: all the B.A. Philosophy grads I know who entered basically any job they could get, often including the trades, and knew during their degree that that would be their path. But wow are they more interesting to talk with and more well rounded than a tech-head who turned up their nose at their humanities prereqs during university and as a result know nothing about the world outside of their narrow field.
Philosophy major here that went from working in a bakery, to sales at a large apparel printing company, to writing and marketing at startups.
I do wonder if CS grads are too often narrowly focused on “tech” companies and not on companies that need software.
