Yep. I have COBOL experience (on a mainframe even!), and I'd even be willing to do it again -- and I'm young by the standards of COBOL programmers, so somebody could even get 20 years out of me still.

But the wages being offered for those roles are abysmal relative to what's available for other skills, and modern life is applying a great deal of pressure to chase larger paychecks, sadly.
