That's an option, but it takes a long time to train and recruit locally, costs a lot of money, and you'll probably have to increase salaries to get the required numbers. If there were an easy and cheap way to recruit all the required staff locally, that would already be happening.
So the solution is to import uneducated and non-certified individuals from other countries at lower pay and hope you can pay them less and teach them? As if that is any easier? Sounds like the only reason is so health conglomerates can provide lower pay.
No, you can import educated and certified healthcare workers, as many European countries, including Switzerland, have been doing for a long time. It’s easier and cheaper, which is why everyone’s doing it.
Fertility rates are low and people are ageing, like everywhere in Europe. There will be a moment that simply there won't be enough workers. The reality is that there is already a lack of healthcare professional even without a population cap that would only get worse given the case.
Sounds like modern slavery, import people from poorer countries to tend to the rich and elderly in countries that made short-term sacrifices to not build a future for themselves independently.
Import people from poorer countries with a salary of 100k CHF and wonderful life conditions. Anyway, what I mean is that it's nor worth it for Switzerland, in my opinion, to break the agreements with the EU to limit the population artificially to a random number.
