In every species female is the selector, that's how natural selection works.
Generally in a group of healthy young population with 50% sex ratio, about half of the men are selected, and they help eachother.
But in the online dating / birth control age this ratio has gone more extreme, and there's no real ,,parenting advice'' or emotional need support that can help, just accepting the new normal for everyone, and competing harder.

Maybe that is true if you are only talking about mammals. But it is certainly not true in general.
Here is an example directly from Wikipedia:
"In the size dimorphic wolf spider Tigrosa helluo, food-limited females cannibalize more frequently. Therefore, there is a high risk of low fitness for males due to pre-copulatory cannibalism, which led to male selection of larger females for two reasons: higher fecundity and lower rates of cannibalism."[0]
This means that in this species of spider is the male who applies the selective pressure.
You can look into sexual monomorphism/dimorphism to find more examples.
