It is a hard labor market, but we’ve been able to hire engineering positions. If you’re not getting applicants, get a better recruiter.
The real issue is our backwards immigration system. We should be expanding immigration when labor is short, not talking about restrictions. If they wanted, they could lobby for better immigration with that $56B instead of giving it to someone who already has hundreds of billions.
Also, many Teslas aren’t built in the US anyway, so there’s not much stopping them from looking elsewhere for labor.
