Oh my apologies for misreading.

It all depends on how Bernie earned that money then. Was it through his own labor or was it through the system of exploitation that is owning and making profit off of the labor of others through having a claim to private ownership over the means of production?

If he makes his money legitimately then no. If he makes his money through being a rentier, his income being primarily being generated through the stock market and shareholder dividends, then yes.

I don't claim to know how Bernie made that money so I abstain from making any speculations. Bernie has been an advocate for shifts towards the left, but the man isn't perfect. Though, he is clearly good intentions so I won't make any base judgements against him until I have more information.

And yes, I understand that retirement and stuff is incorporated into the stock market. That is a giant problem of how the owning class forces the working class to go against their own benefits as a class to ensure their own personal safety and security. That's a much larger can of worms and nuance.
