Maybe you can show me where I can find these 40h/week no-overtime with 30 days/year vacation jobs so I know where to move next.

Overtime is perhaps more about the company and oneself, but in my experience is something you decide to do it or not. If you do it companies pay for overtime. I never done overtime (because companies pay pennies for it :) )

Well that was my point. There's no EU law that prevents you from having to do overtime.

Also agreements with trade unions etc. take care of a sane base-level of holidays and payment.

Germany is also "heavy regulated" in the sense that good people will just choose a job with a competitor who gives you 30 days of free time and paid overtime, although he might pay less.

I think work-life-balance tips slightly over to the worker in a welfare state, because you can choose to earn 100 Euro/month a less but have more holidays AND still have not to worry about paying doctor bills.

That describes every job I've had in Sweden over last 6-7 years or so. But then again I've made a conscious effort to void some of the 'crunchier' industries (like game studios and certain startups), which admittedly does mean getting paid a bit less.

Overtime does happen but French law requires I be able to recover my time (RTT). In my experience there is a mad rush to use up that time before 31/12 so you'll see an additional holiday season around Nov-Dec. Else, it goes away and that time is lost to the fiscal year.
