@Olivier5,
Are you confusing idealism with reality Olivier?
It is a mathematical fact that a large majority of the people working farming, mining, construction, and forestry are male. This is true in the US. I suspect that it is also true in Europe (although I would be pleasantly surprised if there are statistics to prove me wrong).
Our society still has some fields that are predominantly male and others that are predominantly female (not by by law or policy, but just by fact).
