Three-years maternity leave? That's unheard of in western Europe, most countries allow for less than a year (my wife got 6 months in the UK); men only recently started to enjoy some rights in that sense (in the UK it's two weeks).
He talks about a post-50 "protected age" where you can't fire people. That doesn't exist in the UK, where we have the opposite problem (firms firing people near pension age, and then hiring youngsters at 1/3rd of salary). I know in other countries laws are tighter (in Italy it's fairly hard to fire people, for example), but as people say over there, "Facta lex inventa fraus" (as soon as a law is written, a way around it will be found"): in countries with rigid laws, firms now hire almost exclusively on a temporary basis, i.e. they hire people as contractors for years or even decades, abusing the relationship.
The high taxes and pension contributions are also a factor in Italy and in France, but not elsewhere.
What this post is representative of, is the general douchebaggery of European "entrepreneurs"; they usually come from "old money" (banks are very conservative with their lending, favouring entrenched players) and bring a terrible mindset to the workplace, i.e. "screw the employees, they're just idiots anyway". This obviously doesn't motivate workers, keeping productivity low.
