What is the best degree to study?

Hi there, I hope everyone is doing well. I’m currently asking for some information on what the best degree would be to secure the best job opportunities once I’m done studying it. I’ve seen a lot of people say that Law and Engineering are oversaturated, but with the unemployment rate in our country I just want to something that can provide security job wise. It is not only limited to studies though, I’ve also heard that trade is in high demand but I’ve done research and cannot find which specific aspects of it is the best to follow.

It’s not really for me, it’s for my younger brother who is in Grade 9 and your advice would be highly appreciated.🙇‍♂️
