It's an interesting situation that has broken quite a few other pieces of the puzzle. Companies can now raise money while private for a decade. Stock options become useless, because nobody is going to work somewhere for 10 years, or save for the taxes on the options that one can't sell. The stock market doesn't even get to sniff these companies until they are behemoths either. Along with it, the SEC loses power, and aggressive investment opportunities become harder to access for all but the very rich.

Everyone that isn't a venture capitalist of a founder on one of those companies should be concerned about this.
