Help me understand "Elon and SpaceX are going to rob 401k"

I saw "Elon is going to rob your retirement money" in news headline. Can you guys help me understand? Is Elon trying to get SpaceX added to major stock index(such as S&P)? If so, would that affect everyone who owns index funds? Not just people who have retirement funds? Thank you. submitted by /u/LPhermanos70 [link] [comments]
