IE: a poor african child in zambia has most of his shares purchased by an angel investor, and learns that this kid would be able to do some really great things if he went to school, so he pays for highschool/university and in return expects an income from his future engineering work proportional to the share ownership in that person, and then that angel investor is also owned in part by other speculative investors (maybe his parents or his university) essentially fair, accountable and humane bondage.
USSR used the same mechanism (only difference that communist party's bosses took some profit share instead of angel investor's in your example).
There are *elements* of socialism that could be workable, in a voluntary society. But the whole picture? Only if we become something like the Borg. If that's the vision of the future that most people want, I'll be bowing out.
I think it is inevitable! Genetic modifications are need to continue race against machines in the long run, otherwise humans will have no application even in socialism and start degrading when bots do 100% of work.
