Your interpretation of what I said is generally correct. If a tech worker is socially awkward, the he would need a lot of money to overcome that awkwardness. He would need to be near the top of his field. Look at Bill Gates during his days at Microsoft. He used his money and CEO status within Microsoft to get a mediocre looking careerist/feminist. That's the best he could do and that's what he did in a less competitive 1980s sexual marketplace.
A male working in a STEM field making $100,000 - $150,000 per year simply doesn't offer enough to offset the "feels" he's going to give to a higher tier, physically attractive woman by being socially awkward. The majority of guys in STEM occupations are socially awkward. Some might be able to mate if they drop their standards enough.
$100,000 - $150,000 per year isn't going to mean much to a woman with a bachelor's degree or higher who has enough skills to earn a living for herself. His presence at that salary level isn't going to significantly alter the course of her life. She's seeking a certain emotional response that a typical middle of the bell curve in looks but socially awkward STEM worker isn't going to offer her. With her likely level of abundance, she's not going to prioritize the type of guy you describe.
In this sexual marketplace, there are men in non-technical field such as sales, marketing, accounting, finance, or blue collar tradesmen who make $100,000 - $150,000 and many of them also struggle to attract and retain women.
Not necessarily. There are a lot of men out there who are neurotypical and have friends and still struggle in the marketplace.
That's not pleasant for a lot of men. Most men are not excited to cross paths with someone who rejected their in-person approach. A good portion of men can be cordial in that type of interaction but they won't enjoy it. I also don't think most men are excited to see a woman who they had a "one date, no sex, no second date" type interaction with either.
Your thinking is similar to Rollo Tomassi's thinking. Rollo Tomassi has had a marriage last 25+ years but he doesn't think most men in the USA or other Western cultures are in a good position to follow his path in a marriage.
