When he died his net worth was estimated to be around 10 million, but that came pretty late in life. For a lot of his life he was probably comfortable but far from wealthy.
We’re better off not living in world where no one can have an opinion unless it’s on a direct, currently lived experience. That’s some identity politics nonsense.
You can have any opinion you like, but if your opinion consists of passing around second hand sneers, it's a crappy low-value opinion. "It's called the American Dream because you have to be asleep to believe it." - "haw haw look at all the dumb sleeping people being this new". That's not an opinion, not a valuable commentary, it's just sneering.
If you think his commentary isn’t useful, insightful, whatever, that’s fine. But basing your critique on his social/financial position is not good form.
Depending on where you live, if you don’t have 30-70 million in liquid assets, you are middle class (or below).
It's a big club and he was in it.
