You mean here in Switzerland? This is definitely not the case in Poland, where girls have on average better grades all the way through school and I had many such friends and I did not notice any bad treatment of girls.
But I would be not surprised if women were indeed in some way disadvantaged by the system, in some countries at least. But it’s a topic for another discussion.
This might be a result of being disadvantaged, but it also may be a result of genetic predisposition. That’s what Jordan Peterson is on about, and it’s what feminists hate him for. Women are often not motivated by things that are required to become a billionaire. There is a greater concentration of male geniuses than female geniuses at the end of the bell curve.
And one final thing to touch upon. No problem if a woman inherited the fortune after her husband’s/father’s death. But inheriting billions as a result of a divorce seems highly undeserved to me. It’s weird that so many of these divorced billionaires did not sign any prenup agreements. I know, being a “housewife”, not being able to pursue your dreams, not seeing your husband because he works his ass off, it comes at a price. But IMO it’s not worth billions, not the half or even a quarter of his entire business.
