Natural selection still happens for humans. Natural selection just applies for our current environment, not some ancestral environment. It's not longer selecting for the ability to outrun lions. It's selecting for the ability to attract a partner, to want kids, and to secure a place to raise kids in.
Citation needed. The ability to survive doesn't seem tied to anything you mentioned except maybe to working genitalia, for example if you are born in a country with good health care (e.g. Canada) you are more likely to survive than a country with bad or mediocre health care -regardless of any other criteria-; wanting kids and having kids are not as correlated as expected, is easy to see that in the tons of unwanted teenage pregnancies, "attract a partner" is so subjective that it doesn't lean to any population in particular, you can see that when even male meth-heads living in SUVs have a girlfriend with similar issues; in general healthcare has improved so much that now lifespans are pretty much leveraged regardless of most other variables meaning is likely natural selection no longer plays such a major role as it did in previous generations.
Does it really? Humanity is very very keen on keeping alive every individual, even the most disfunctional ones. Not only that, but also try really hard to let even the disfuntional individuals procreate. To me it looks more like the opposite of natural selection. After all natural selection is not only about the best and most fit individuals but also about the pool of genes of the species also.
