No. I assume the greedy motivations of the many is the best path towards progress. Any other attempts to replace this failed miserably. Ignoring human nature in ideologies never works.
That's extremely difficult. I just don't assume something is impossible because it hasn't been done yet. Especially when there is an active battle to undermine and destroy such ideas by almost every powerful entity on earth.
We know that none of the goods you listed would be available to the masses unless there was profit to be gained from them. That's the point.
I have a hard time believing a large group being motivated and mutually benefiting towards progression of x thing would result in worse outcomes than a few doing so. We just have never had an economic system that could offer that, so you assume the greedy motivations of a few is the only path towards progress.
