With health insurance connected to your employment, references checks, previous salary leveling, noncompetes, the interview process.. the American system doesn't make it easy to get another job.
Yeah I felt bad for writing the comment a while back “if you want a big vacation just take time off between jobs” and then I realised in the US that means you’d probably have no health insurance for that time.
I saw another comment saying you need more than 10M to be truly financially independent in case you get sick … to a single person!
