1) Medical = because it made you rich and get prestigious degree!
2) Engineering = look smarts and important, and also, to be rich and have prestigious degree. MEH!
3) Law = Lawyer's and its all prestigious job + degree.
were the prestigious job or majors are just Doctor and Engineer and Lawyer?
I said this because there's a local unwritten law and local norm/ custom In my local circumstances said that if you're a Doctor or a Lawyer or an Engineer or a Person that works for Government a.k.a Civil Servants, you are so great. That's the REAL JOB. That's the whole point you go to college and get yourself a REAL JOB for a REAL WEALTH and MONEY. Because when you're older, the Prestige get you on the top.
"What about art?"
They said, "Art is just for hobbies. Art won't lead you anywhere. Art's not bring you for future wealth. Life's all about wealthy. To be wealth, we need : Prestige, and of course, Money.
those opinions are unfair. You can't judge things by its commercial's succeed. Everyone has opinion. Everyone has different mindset to stick on. There's no good or bad things, that's just depend on everyone's perspective.
