You tell me. I work for an insurance company that bet the farm on Forté's 4GL technology (then bought by SUN and renamed Unified Development Server, and then killed).

so I'm stuck maintaining a few hundred applications which are hacks and workarounds on top of the obsolete enterprise software.

The pay is very good for my country but I'm looking for my way out.
