People blame the crap dating scene in the West on, like, delusional people or dating apps but I think the reality is its a lot simpler and yet also much harder to fix:

People aren't mixing enough because they don't know how (guys and girls aren't going to the right places to find one another, and if they are it isn't often enough). There's a lack of assurances. Basically, girls don't have an assurance some guy won't try to get in her pants if she gets too close, and men don't have an assurance the girl won't be a total bint.

All the other stuff (having families being expensive, social media warping people's minds, etc.) is just an appendage to these central reasons.

And the only way to fix it is to make sweeping societal changes aimed at reconstructing former norms of things like modesty, abstinence, chivalry, etc. Obviously, these changes are downstream of policy and general demand, and you can only really act on the policy side of things but that's just not feasible because it would mean things like regulating dating apps or clubs or sexual behavior and that's just not feasible in the West.

So the only solution is to sit around, waiting until everyone gets fed up and rediscovers why we had the norms we did in the past. And then they can reject a lot of the modern slop and return to tradition in a genuine sense, not in this parody sense like we see with those idiot trad wives.
