BTW, I work with an 80-year-old who still works even though he could comfortably retire. We have special technical skills that are typically in demand, particularly by defense firms. I'm taking grad courses, on my company's dime, of course, to expand my knowledge and make me even more versatile in the job market when I start looking around for another position.
There are a million stories ... of lost work and retained faith... I hope your friend finds a way out... and your plan is a good one — make yourself versatile - look out for trends and new opportunities ....
An HR/Recruiter could start a home based - internet based business - recruiting specialty type employees for various firms... a personal touch... perhaps not high volume - but with lower costs operating from home - perhaps it would work.
