马斯克谈特斯拉SpaceX财富观：以创造价值为核心

Correct.

My Tesla and SpaceX shares, which are almost all my “wealth”, only go up in value as a function of how much useful product those companies produce and service.

This means my “wealth” can only increase due to producing more products and services for the public. Moreover, anyone else who is a shareholder in Tesla and SpaceX, which includes employees, participates in the upside of stock appreciation.

That is because I am a maker, not a taker like the Bernie Sanders type politicians of the world. They take and they're on the take, because they cannot or will not make.
