Changing work place every year or 2 sounds exhausting. Expensive too. 

Stuff like this being necessary to have a higher wage also doesn't help with fertility rate of the country.

Some people don't mind changing, at least in that regard. And while it's not necessary (you can always just ask for a raise, and since employers know well that mobility is high in our field, they will grant it if it's reasonable and if you are worth keeping), I think it's pretty normal that you can get the best deal if you can find the company that is currently most in need of your skills.

I have a different approach for many reasons; luckily I have found (or let me say chosen, at least in part) a boss that values me. I would surely have a higher wage if I had been more of a mercenary, but that's not the only thing I rate about my job.
