It's like Musks duplicitous argument about unlimited abundance. We have a lot of abundance now, we just keep accelerating it all into the hands of fewer and fewer people - whose response is only to want more, and more, and more.
Wealth in terms of capital doesn't represent material goods, it represents the system's confidence in your ability to direct capital efficiently. But eventually efficient capital bottoms out at consumable goods. Someone like Musk with a lot of capital under his control is contributing to the end goal of unlimited abundance.
In a free and fair market, his capital would be regarded as a deeply inefficient distortion.
The end goal is unlimited abundance (for a handful of people).
Let's not pretend that capital is actually directly efficiently, tulip.
