It seems warm and fuzzy to think Sam, and the implicit company he keeps (the ultra rich)--who are "leveraging not only their abilities and luck" but already accrued wealth--can and will redistribute it. Anyone who wasn't born yesterday will simply laugh at this prospect.
I'm not sure why Sam feels the need to call what most of the world is doing worthless. I think it's crude and indicative of a narrow social and cultural experience (which surprises me considering his position).
Believe it or not, there are cultures and groups of people who do not revere technology the way most North Americans do.
Also, a good exercise for Sam (and others possessing a similar world view) might be to think about how many "worthless" people and jobs it takes to accomplish the things he does (including this blog post).
