Please stop doing that, comparing the USA to some fictional country called Europe to prove a point. I agree with many of your arguments, but where the author of this piece is generalizing based on anecdotes, you're generalizing based on stats. And opportunistically picking and mixing stats from different countries on top of that.
For someone who likes to throw around stats and pretend to make a scientifically based argument, what does a conclusion like "most European countries are behind the USA" even mean? Europe has countries the size of a few football fields. It has large, thinly populated countries, small, densely populated countries and everything in between.
I would really appreciate it of people would stop using this fictional Europe for their ideological political arguments about the USA.
Full disclosure: I happen to be from a country in Europe that has higher participation rates for women than the US, is not Scandinavian, doesn't have particularly strong supportive policies (better than the US, but that isn't saying much) and on top of that: despite these stats women in this country are leaving the labor force in large numbers when they get kids, which particularly shows up in a lack of women in senior leadership positions. These things vary wildly per country and culture.
