We already have eugenics in place, it's not just a theory...
It works something like this:
Those that have this thing called health insurance get cared for and live.
Those that don't have this magical card don't get cared for and die.
Can't you see it's transparent wisdom!? Passive Eugenics is teh BEST, especially when based upon something as socioeconomic status. Blessed art thee ass-kissers and business moguls, may they have more opportunities to spred their genes til poor people are no more. Amen.
