This whole current moment rhymes too well with 2000 and 2008. Who are the Ken Lays, the Bernie Ebbers's, and the Madoffs? I suspect Bezos and Musk are going to fall hard.
eventually everything goes down. amazon has gone so high, bezos has so much money, he'll be fin even if it goes down by half. he'd only have 60 billion. musk has much less but plenty too. space x and teslas are incredibly inventive and creative companies. they are also companies with only a limited monetary product stream. so they are vulnerable to having a few problems in a row. Even if they get problems fixed eventually it could hurt them. but my feeling is both companies will continue to generally succeed, even if they don't always make their schedules.
