I think it works from the other side too. Many Japanese employees have come to expect a system of lifetime employment and do not tend to jump ship as easily or often as say, American employees. Even if this means lower compensation, the stability is considered to be a better factor.
Except for some of the earliest employees who are literally invested into the company, will Tesla really have "lifers"? Even amongst these, I think most of them will act in a much more mercenary way (both in terms of compensation, as well as career ambitions) than their analogues at Toyota or Honda.
On the opposite side, I don't think many of the non-Japanese employees and executives at a Toyota or Honda expect their gig to be lifetime employment either.
