The suckers being fleeced are every pension fund in the world. They're demanding the S&P includes them faster to force ETF owners to buy in before the price tanks.
Why are they being fleeced? If people didn't want to buy SpaceX they could buy some other ETF that doesn't include it. If there's enough of a demand I'm sure ETFs will be offered which include all the big indexed stocks except SpaceX.
God forbid we participants in the stock market evaluate a business before investing in it, or do any sort of work to get the return we're promised.
I, for one, much prefer to earn a 9% return without expending any effort or thought at all.
