Interesting assessment. I agree for the most part.
1. they care more about their career than men
This is more a function of the cost of higher education. Women with BA/BS degrees or higher act like this. Women with high school diplomas/GEDs or associate degrees do not act like this. A higher percentage of women now get BA/BS degrees or higher since 1980 or 1990. Also, after age 25, more of the singles are the BA/BS degree holders as women with lower levels of education tend to marry and/or have babies sooner. It also tends to be the Non-Hispanic White women who are the most career obsessed, since Non-Hispanic White women tend to have more of the higher education degrees.
I've interacted with a few Hispanic women 25+ with BA/BS degrees or higher than were career obsessed and that was annoying AF. It's expected that Non-Hispanic White women will act as unfeminine career women but that's not an expectation for Hispanic women. Part of the appeal of the Hispanic woman is that she won't act like a White woman.
2. they become increasingly selective as their estrogen levels drop and they start to become more "analytical" in mate assessment
Partially true, when they are evaluating men near their own age. If you are a 20-24 year old man and you approach a woman in her mid to late 30s, she won't act super selective. If you as a younger man present a strong sexual frame, she'll have sex with you quickly while she'll make similarly age men work more for her vag.
I can see this as true. Being hardened from relational disappointments can produce poor body language and IOI signaling. Additionally, a lot of the Millennial generation has been poor at sending IOIs due to technological immersion, which is why some guys spam approach without IOIs.
I have a friend with a mid-30s wife (married a few years ago) who I saw recently for the first time since the pandemic began. Holy smokes! Her mid section was round, thighs seemed thicker, and just more all around body fat. She seems like she's gotten too comfortable in her relationship (over 10 years long now). She's ballooned up without even having kids!
Personal story aside, this is often true.
6. they don't have the time or energy for clubs resorting to online dating which becomes a useless time sink of bots, dik pics, and hundreds of thirsty random average guys
What's wild about this is that she'd probably save time if she got off of the apps. She would get approached less in person. Without swipe apps, she'd realize her lower market value and start to get into better shape to realize her value as best she could at whatever age is. When she puts herself on swipe apps, she generates a ton of interest, mostly from thirsty random average guys who she won't settle for while she's pumped and dumped by hit it & quit it guys. These "hit it and quit it" guys are guys with SMV higher than hers who appreciate getting the pusssy from her but don't want to be with her long term because her SMV is lower. However, her perspective is skewed by the immense attention (which is intoxicating in a way) and the random bangs with hot men.
tbh I think 24-26 is the most toxic, and they get better afterwards. Not as good as 23 though
I don't think women get better in their 30s.
