Rewarding the reckless egoists is immature, it demonstrates a lack of understanding of the larger system, and by not addressing or acknowledging this issue we get our current situation. Knowing and not fixing is immature.
The problem is that the rewarding is systematic and can't really be attributed to a single person (or persons), so calling it immature is really just hitting at strawmen.
You disregard too quickly. Just because immaturity is systematic does not erase the fact that immature behavior is radically short sighted and a personal failure to navigate reality.
