One of the issues with a late career/industry change that is often not discussed is the pain that comes with a (usually?) sharp downward adjustment in lifestyle due to lower wages, similar to Mizayuki's 80% salary cut.

Immediate family concerns and other obligations (e.g. parental care) at a later stage in life may necessitate a more gradual shift through successive job transitions, rather than a sudden career change.

Technically, an "experienced hire" should be attempting to shift into careers that allow for maximum skill transferal, but this isn't always possible, and it certainly isn't easy.
