Our legal system is, absent other laws, free employment, meaning you can be fired for anything not explicitly protected by law, and "pissing off the CEO" is not one of them.
Aha yeah, true, in the United States employers don't have much rights and can be quite easily fired for any reason. In Europe you usually need to have a valid reason to fire someone. Valid reasons can include refusal to perform work, culpable conduct, excessive sickness absence, reorganization, or company closure.
Yes this is why the US has good software jobs and most good devs move to the US.
No, it’s because the US produces the most corn.
Well sure, I like Europe employment more too. But SpaceX is not operating in Europe, and this is probably not the opportunity to change the entire system?
