These aren't new economics, it's just VC funds trying to boost their holdings by saying it's worth X because they said so. Frankly the FTC should make it illegal.
But yes, I would totally love to invest in startups with people's pension funds. It seems like the perfect scam where the only losers are the public that allows such actions.
But more to the point, I was talking about how you apparently think VCs just make up super high valuations of the companies they invest in to justify those investments? Are you not aware that VC is a competitive market?
