Yawn this tired old yarn, again. Mainframe development was offshored from the US decades ago. These retiring cobol programmers simply don’t exist in numbers that matter. The market could be to the companies doing the offshore work, but they’ve been throwing bodies at this problem for a long time, maybe there’s a market there maybe not.
