The not commonly used U-6 is, yeah, but even your link mentions that U-3 is commonly used, and why would you compare different unemployment rates between countries? Here [1] is Destatis from December 2022 with data for all EU countries and the US for comparison.
> Spain, Greece, Italy's unemployment is highly seasonal - in summer it drops to almost 0%
In June 2022, Spain had 12.6% (2021: 15.3%), Greece had 12.3% (15.0%) and Italy 8.1% (9.4%), see [2] from Eurostat.
Is this going to turn into a session of frantic googling to find numbers that support your claim that you based upon feelings and prejudices instead of facts?

Not a paradise, but not a hellhole.
But that's besides the point, the claim was that employment has something to do with it, not the extent of the welfare state.
On the other hand, a lot of things influence employment beyond labor protection as well.
