If you know COBOL and know other languages and are fluent in "current" tech, then I see nothing wrong with consulting for $300 an hour doing some COBOL.

Company I work for still uses AS400, which has been released in 1988 just after I was born. We have a dev who supports it. This isn't a small company either.

COSTCO is still using and a lot of huge organizations.

I'm focused on newer tech C#, .NET, Blazor but I do interact with DB2 database which is the backbone of that old system.

At one of my interviews somewhere I mentioned that a lot of apps I'm writing are just extending AS400 and the dude interviewing me was really hyped up. He has spent a lot of time with the green screen in his younger years. The job had nothing to do with AS400, but that conversation got me an easy offer.

Most consultants cannot get $300/hour for COBOL though. It is those who have specific other knowledge - like experience in the system before they retired who can get that much.
