This is a ridiculous and blackpilling statement, and no it's not the truth, especially not without a qualifying statement. You could say the majority of men will not get that young tradwife who submits, and as a result you will have a quarrelsome relationship. You can also say men will end up having 30+ year old women settle with them due to the brainwashed nature of women only reacting to nature at the very last moment.The bottom 50% of men will never get a woman.
I'm well under 33 and met a wonderful Christian woman who is actually on this forum, married her, and had a son with her all in just over 3 years. You're right, it is difficult to do this now, that's why credit must go to God. People who have this blackpilled mindset are off-putting to women, and often view women as nothing special, as if any woman will do. They hate that, they want to feel unique. If you treat them like a checkbox, just a life milestone, something to get over with and move on, that is not a path to happiness.
One factor that will push more women to humble themselves and submit to men is the coming economic hardships of this decade but that is better discussed elsewhere, suffice it to say, young single men who learn a blue collar skill or trade will be in a great position a few years down the line.
We also should look at what worked in the past, what enabled men prior to the 1960s to get good wives? That is something to think about. Most of the answers are things single men can still do.
