Why do some smart high school students want to do research?

Note: I am talking about NON-AMERICAN countries where you can major in Medicine, Law, etc as an UNDERGRADUATE)

Some high school students who got extremely good grades in their finals (i.e. Good enough for Medicine in non-American countries) decide to major in stuff such as Linguistics, Physics, Anthropology, etc. In the hope of doing research in the future. Why would they pick that?
-If you don't have anything published, your funding will be cut and you will have no income
-There is no guarantee that you will like research and most people hate if over time
-Jobs are meant to be monotonous, not fun
-They can easily major in Medicine, Law, Actuarial Science, Dentistry science, etc and switch to research later on or do a Master's degree in their area of interest
-The market for researchers is very bad at the moment - it is 100+ people competing for a tenured professorship post and it will not be you getting that job
-Being an adjunct professor sucks as all the contracts are short-termed
-It is hard to even secure a mortgage with such unstable employment
-If you can't find any professorship job, it is hard to find anyone else to hire you as they know that you will go back to academia as soon as you find another professorship job, so chances are you will either end up unemployed or working at McDonalds during this time
