It's actually low income vs. high income. Low income is less than 200% of the FPL while high income is at least 200% of the FPL. So no, nowhere close to the top 5%. Now are you appropriately shocked?

So $60k~$70k/yr is now rich? All this is telling me now is that if you're at least middle class, you have a good chance of maintaining the standard of living that your parents gave you. I don't see that as a bad thing at all; worst case, I see a problem in some people growing up in poor environments so socially toxic that it hurts their chance of escape.
We do not accept that we will attempt to reduce the reproduction of citizens we decide are 'undercapable'. The history of eugenics movements and their results should be all the evidence you need as to why that's a really, really bad idea.
Nah. Hitler was a jealous failure that described the genius of many Ashkenazi philosophers, scientists, etc as "Jewish philosophy" or "Jewish physics" because he and his buddies were insecure about not being capable of understanding it, and it's a shame that the concept of eugenics had to be ruined by him. The Ashkenazis are actually a great example of the success of (albeit probably unconscious) eugenics; an insular culture that placed high value on literacy and filled niches in banking and elsewhere not permitted in the Christian/Muslim societies they lived with. The extent to which their success is genetic versus cultural is very debatable, but afaic, culture is the transmissible information that makes humans so unique over other animals. A white West Virginian and white Connecticuter could have similar genetic backgrounds, but if one grows up wanting to make coal miners and the other engineers and scientists, I know which one I want reproducing.
I'd argue that the underclasses being the first victims of war and starvation whenever shit hits the fan is better evidence in support of birth consciousness. Granted, technology has pretty much eliminated starvation except in areas with terrible government, but it's always better to have too few people than too many.
Since that only contains the abstract, is the primary cause due to teenage pregnancy resulting in dropping out of school? I'm all for making birth control available, in case it's not obvious from the rest of my post. A few hundred bucks on contraceptives/sex ed to save tens/hundreds of thousands of dollars to society overall sounds like one of the best deals imaginable.
