What "equal right" do you mean, that "equaled opportunities in the labor market and education"?
Also you seem to miss on the fact that men get worse grades in school (which some say is because of discrimination), which makes it harder for them to enter university.
It's a big ass cool world we have going on, and starting a family effectively ties you down from being able to explore it.
Good grief.
Women don't have the same financial expectations as men do. This is true even today, despite all the push for equal pay and equal rights. Often, that's prior to even getting into a relationship. If you seek an indication, ask a bunch of guys if they would settle for a girl still living at home and then ask the inverse, both groups aged in their 20s.
Given how men are increasingly "giving up on society" because of these standards being harder to achieve every day, GP's argument isn't that improbable at all.
You sound like you have some preconceived notion of you or your friends being wronged by women or something that I'm not going to be able to shake or have a reasonable discussion about.
I will however say, in words that may appease your ideology - it's honestly never been easier to get a banging hot girlfriend than in the current climate. You literally just have to not be completely fucking weird, have a hint of how to dress in something that compliments your figure, have the smallest standards of 21st century developed country hygiene, and one ever so slightly interesting hobby. Seriously, women will throw themselves at you.
But keep telling yourself what you want to think and reinforcing your views. I've honestly felt nothing but bad for women in STEM lately after an internship as a MechE in a fairly large and well known company. The older men acted fucking disgustingly towards the female interns, when all they're trying to do is make a career in STEM.
Nobody says you have to do that, but if some men and women want to do it, it will show up in the statistics.
Also even if you don't want a family and just want to explore the world alone, you don't need that much money. What exactly, do you want all the money for, that a high end career would give you? Also working 60 hour weeks would also prevent you from exploring the world, wouldn't it?
