1) This is anecdotal evidence but as far as I know it's difficult for non-EU people to get a work permit in Switzerland. I know quite a few students that completed the CS Master in ETHZ and that are from Egypt or China, etc. that could not get a job in Switzerland because it was hard to get a permit. Similar for Indian students that did their ETH Master in mechanical engineering, etc. All the students that I know wanted to stay and work in Switzerland. 2) Again, I might be wrong, but I feel a number of CS PhD students in ETHZ and EPFL are getting paid by European programs (e.g, ERC). So, it's not necessarily Swiss taxes that pay these people. 3) At the end of the day, the Swiss government or any government is making an investment on those students. As any investment, it might be profitable or not. Some students might stay in the country and pay back the investment by founding companies, getting good salaries and paying higher taxes, etc. versus some students that might just go back to their country. Actually, to me, it seems like a pretty good investment. If some student studies in China and then comes to Switzerland, Switzerland might have to pay for his/her education for a Master and a PhD, but Switzerland never paid for his kindergarten, primary, high-school and college years, etc., because for example China already paid for this. 4) Most of the papers getting published in universities (at least for CS) are published due to the hard work done by graduate and post-graduate students (with the help of their supervisor of course). Even if the students decide to leave Switzerland afterwards, they still increased the research-throughput of the Swiss university in which they worked. I believe we can agree that, that in itself is good. |
5) There are scholarships for young Chinese scholars that are co-financed by the ETHZ and the China Scholarship Council: https://ethz.ch/en/the-eth-zurich/global/eth-global-news-eve...
