Everyone wants an old school love life, but no one wants to put in the effort, why?

I know in some places, discrimination is still alive on skin colour, religion etc.
But keeping those aside.
I can tell men want it, ready to put in that effort.
I can tell women want to do it too.
But why don't they meet up and start those efforts.
But in my perspective they cross each other everyday but no one wants to get scammed.
Men are scared that the women will say something"we are just friends" or rejection

Women are scared of crime against her will.
Even if she knows him more than that.

Or just too many options through apps (those apps are only good for good-looks) an avg man never finds someone on that (very rare).
