It sort of makes sense. A stronger EU safety net means less burden of future proofing lands on each employee. That's bound to make those employees more competitive.
In the US, I have to consider the possibility of an uncovered black swan medical event in my family's future, since our medical safety nets are poor. As someone who can demand more money, you bet your ass that my employer gets to pay for ways to reduce that risk to me.
If I were a EU citizen, I suspect I wouldn't be worrying about it, or carrying so much insurance.
