I think human
colonization of the cosmos should occur with 3 classes of ships... the A ships for all the leaders and scientists and great thinkers, the C ships for all the workers and the doers, and the B ships for everyone else
And we send the B ships off first.
Imagine that.. an earth free of politicians, cost expense accountants, advertising execs, religious fruitbats, and virgin media call centers......
