But now that we've escaped the starvation etc, I'm suggesting it's time to change the paradigm again. Once we've crossed the river, we don't need the boat anymore.
1) A few billion people wouldn't agree with you suggestion that "we've escaped the starvation." They might not want the boat to be abandoned just yet.
2) Wealth is generated on a gradient, in perpetuity. It's not a "we have it" or "we don't have it" phenomenon. Thus the analogy to "crossing a river" is not appropriate. There is no finish line.
