A high reproductive rate is only successful in the short term, as I see it, but is doomed for failure in the long term. I think this is why people don't commonly have twins, triplets, etc. when they give birth.
Say you have 2 powerful people who, just as an example only produce 2 children, so we always have 2 powerful people. It's a bad example, but follow me here. Say you have 2 plebs who reproduce as much as possible and after a few generations say have 1000 offspring. Now we have 2 vs 1000, but the numbers for plebs mean nothing if there is a food shortage, because the powerful people ensure their supply while the plebs die.
I guess it's a little stupid to speculate on the future of the human species, because the conclusion you come to depends on your political view of the world. I think the difference between us is that I view the power/blue-bloodness you inherit heavily influences your evolutionary fitness and you don't.
