Basically everything that gets you a decent paying and stable job if that's what you're after: STEM, law, medicine, management consulting, banking, finance. Did I miss any?
I'm sure we all have our suspicions about which degrees lead to better careers, and which are luxury purchases, but it would be nice to have some data to prove it.
law in most countries unless you get to sucessfully practice on your own or as a partner of a firm doesnt pay well. Banking/finance is similar to a lesser extent with few good positions open compared to the talent pool.
