Have they seen European salaries?
Even if grants were resumed tomorrow, the fact they ever paused, at all, for capricious political reasons, means there isn’t good job security, even if the salary is good.
European academia is usually constrained by the lack of funding and permanent positions. Many European researchers end up in the US, because it's easier to find a job there. Partly because it's a big country and the right kind of opportunities are more likely available at the right time. Partly because American researchers are more likely to end up in the industry, because the salary gap is higher. And partly because the American immigration system makes it easier for foreigners to get an academic job than an industry job.
But we also like to joke that we are in the US, because we are not good enough to get a job at home.

I don't know what the salaries are in Bio, but with regards to developer salaries you can live a very comfortable life on a "low" European developer salary (excluding perhaps a few countries with deeper structural problems such as Portugal).
