Elon very likely lives in his own bubble with no one around that can disagree.
A millionaire could surround themselves with other millionaires and get a reality check. There are few billionaires and trillionaires, and they are likely surrounded by people that depend on the billionaires for their life’s stability.
This is a good argument for taxing billionaires heavily. They should not exist and will be destructive as they loose touch with reality.
This is also a good argument for not allowing parallel societies for different income levels or similar distinctions to develop in other parts of society which means we need to get rid of isolating factors like car commutes from inside the garage to inside the office parking garage at work. People with different income levels should interact regularly in an informal setting where they can actually talk to each other.
The only thing insane would be to let Elon Musk exploit them.
If Musky, and capitalism, is/are sane then being insane is just fine.
Every accusation is a confession.
