your chances of finding your "dream wife" would not have been better at an Ivy League school. Quite the opposite, in fact. Women who are attend Ivy League schools tend be less attractive than average, more feminist than average, and more entitled than average.
You're correct. If looking for an extended, committed relationship (doesn't even have to be marriage), you're better off looking at a basic state university in the USA as compared to an Ivy League school. A woman with a BA/BS from State U is less likely to be as big of a feminist/careerist than a woman with a BA/BS from an Ivy League school. Her less feminist/careerist orientation will make her at least a better in the girlfriend phase of the relationship. If you put a ring on it (a risky proposition for either State U woman or Ivy League woman), State U woman is likely going to be an overall better experience. You might get divorced from both State U woman and Ivy League woman, but the overall relationship will be better from State U woman.
Women with advanced degrees from any school are bad options for extended relationships.
If you want a more feminine woman, you want a woman whose maximum education level is a bachelor's degree from a public state university.
If you can get a good woman who has a lower level of educational attainment than a bachelor's degree, then that is the best option. In the roughly the second half of Gen X (1974-1981) and Millennials (1982-1996), women with lower levels of educational attainment tend to come with their own set of problems. Many of them had earlier in life failed marriages that led to babies being born, so there's a decent amount of single motherhood. Unless they went to trade school for something like dental hygiene, medical assisting, or maybe some IT work (rare), they might not have anything going on career wise. I know most men don't care about a woman's work. I don't, but a woman who is unstable at work is often unstable in their personal life. Unstable women in their personal lives are often big drama, which most men don't need. I anticipate that Gen Z (1997-2012) is likely to be similar as more mature. With women born prior to ~1974, there were plenty that had more going for them without going to college.
If I had learned Spanish in high school instead of French, I think I would have seriously looked into GeoMaxxing in Argentina; amazingly, next-door Chile is almost as bad as Canada for chicks.
I've never heard that Chilean women were like the Canadian women of South America. Chile has been one of the strongest economies and most stable governments in Latin America in the last 50 years.
In the early part of the 20th Century, Argentina was the pride of South America, with a stable govenment and prosperous economy. Buenos Aires was as advanced and cosmopolitan as Western Europe. Argentina has been a mess geopolitically and economically for a long time. The military dictatorship era of 1976-1983 was one of the low points, as was the 2001-02 era in which they had 5 presidents in a 2.5 week period. Argentine women tend to be quite difficult as well. Since Argentines like to think of themselves as Western Europeans in Latin America, they can act a lot like Western women.
Colombian and Venezuelan women tend to be the most physically attractive women of the Spanish speaking nations in South America. Those countries have been a mess in terms of politics and economics for decades.
The majority of women in South America are native Portuguese speakers due to Brazil. Brazilian women have a good reputation too.
take a yoga class, dance class, or gymnastics class to network with more women (these classes are usually overflowing with fit single women),
Fitness classes can be a good option from the perspective of ratios and avoiding earbuds. The most difficult thing at fitness classes can be actually getting women to engage. First off, you have a narrow window of 5 minutes before class and 5 minutes after class to do approaches. You might be able to make good eye contact and do some body language flirting during the 45-60 minutes of a fitness class. The biggest challenge is that a lot of the women who attend classes aren't that talkative before or after class. I have gotten dates from fitness classes so it's not impossible. It's not as fruitful as it might seem given the ratios.
