Not sure why anyone would want to continue to work for this petulant bully
Yes, I get the H1-B serfdom issue, and it's not uncommon for people in the US middle class to be living paycheck-to-paycheck and want to be sure of another position before leaving. (I wouldn't have much faith in Musk's severance-payment promises; that money has to come from somewhere, and the $12K or whatever that employees are prioritized from bankruptcy proceedings won't go far.) But actually want to work for this idiot? There can't be many left.
I've been reading Miller's Toy Wars (1998) about Hasbro and the other big US toy companies, and I'm struck by the difference between the execs he writes about and Musk. Those were people dedicated to their firms and employees, actual visionaries who created innovative products and marketing strategies. Ruth Handler cooked the books,1 but she was the co-founder, co-chair, and president of Mattel. She invented Barbie. She created her first business from nothing, peddling decorative boxes her husband made in a home workshop at local boutiques. Hasbro's Hassenfelds essentially invented using children's television programming to market toys. Maybe you think all of that contributes nothing to society, but hundreds of millions of children beg to differ. And it was innovation.
What's Musk done? Bankrolled Paypal (ugh) in the early years, and gone along for the ride on Tesla and SpaceX, while wasting money and energy on quixotic side projects. Any already-wealthy entrepreneur could have done that, and I don't for a minute believe Musk brought anything special to the party. He's a beneficiary of a historical moment, and someone else would have played that role if he hadn't been there.
In The Ascent of the A-Word (2012), a cultural history of the term "asshole" in US discourse, Nunberg remarks that Donald Trump is probably the quintessential asshole, as popular usage has constructed the term. I think Musk may have since refined the category. Sure, Trump managed to get himself (or was placed by his handlers) in a more dangerous position; but for sheer assholery I think Musk has him beat.
1Her 41-year (!) prison sentence was suspended, but she and her husband lost control of Mattel and about half their personal fortune was returned to the company. She went on to found a successful business making breast prostheses – she was a breast-cancer survivor herself.
