Genetic evolution wouldnt stop. But in our world the less fit ones would
not get eliminated but would simply go down the economic hierarchy.
If you look at how women choose their grooms you can see that they make a
fine balance between economic compulsion and what they perceive as
advantageous traits.
With time advantageous traits like intelligence and other attributes will
start floating towards those higher up in the ladder and less desirable
things would gravitate down. But it would take millenia to see the effect.
However you cannot strictly call them as new species since they all will
be genetically compatible for mating. But with the kind of churnig that we
see , poor people will not only become poorer economicaly but genetically
as well in due course of time.
Any one in the lower strata who does well will move up the chain bringing
the genes up in the chain.
Look at my background. I am a first generation graduate but has gone much
farther than anyone in my whole native village. I must be grateful to my
ancestors who gave importance to education (my parents couldnt study
further due to financial reasons although they were good at it) rather
than economic qualities. People from my village who were economically
beter off some 50 yrs who couldnt do academically well have gone down both
ways.
Better genes would accumulate in the better off populations were there is
freedom to move vertically.
