Accepting that theory as true implies that there are also people without the drive, skill and resources and what is to make of them? Are we not all created equal? Should we not have equal opportunities? Should these lower-people be helped? Do they deserve it? Do they "earn" to not earn a lot of money because they are born from the wrong mother?
