>Even if your dad's skills are in a specific dying industry, he probably has some transferable skills which others want to learn.

My dad is in a similar predicament being, well, a shady dealer in a troubled part of the world. Unfortunately for both him and myself, he doesn't want to leave his "industry" despite the diminishing returns and the risk or prison (he has never been in prison). Even if he wanted to his industry probably wouldn't let him leave.

Posing this from a throwaway account for obvious reasons.
