Or quite the opposite?

These engineers may find once migrated (especially after a few years, ie slightly older) that the option of having children not to be burden in such a system, might find the safety net of not worrying about health and insurance increase their ability to focus on being productive instance of simple grinders, especially if well educated and motivated.

So, they will pay huge taxes to finance the public education system they didn't benefit, while at the same time repaying their student debt because they had to pay for university in their own country? I don't quite follow the logic...

If you live in a society, you benefit from its education system even if you didn't attend it, as all the folks who were educated in that society's educational system are the rest of the folks who contribute to the economic system and its health and robustness.

I didn't judge in my comment if it is good or bad to organize a society based on these values. That seems to me to be a bit unrelated to the situation at hand, where you have to move across countries and switch different systems. That fact that you may end-up paying "double" is what I was raising.

Taxes is for more than just education!

Anyway, you will benefit as your friends, colleagues, neighbors and especially your own children will not be burdened with the debt, and more likely to be well educated.

Isn't education the largest part of state spending in France (not saying it is bad thing, but still).

True, it probably is a large chunk though not sure if largest.

For example in the UK , education is about 1/6. Where as over 50% is NHS, welfare and pensions. (and only 0.3% is spent on unemployment)

Sure, if you plan to never get sick, have kids, or get laid off. Or if you're not trying to settle in one place.

I hope you enjoy your work culture if all of your colleagues are engineers in their 20s who never take vacations
