Recruiting is not the sole measure of workforce health, retention is an important component and overall stability is as often effected by the latter as the former. Part of the deal when you win mission-critical contracts is that you agree to oversight, and workforce stability is an oversight issue. Repeating myself, workforce disruption which threatens government missions is absolutely a government concern.
Have we learned this? Sure, Elon's said some things, I'm not entirely sure what level of seriousness one should ascribe to them. I do remember people bemoaning FWS having a say, and insisting that they were simply a beard for a "vengeful" administration determined to kill a company they keep giving contracts to. Instead it appears the team worked as fast as they could and now SpaceX will get a greenlight within days.
I said noting about outsourcing, shipbuilders and aerospace made plenty of silly mistakes with their workforces before even getting into an outsourcing discussion. I'm talking about retention, not just of people but of knowledge, skills, and practices. Skippy with a shiny, new 4-year degree may be enthusiastic as all get out about getting hired by SpaceX. might agree to whatever pay, benefit, and hours are presented just for the chance. But Skippy will need people who actually know what they're doing to provide the training and institutional know-how to get up to speed. If those people aren't around because SpaceY comes along offering space work with less BS, the company's going to struggle to get people like Skippy to the point where they can keep things moving.
