Oh, that. It's been going on for several year in IT (and as SP says, decades if you count builders etc; centuries if you include textile workers etc.)
It doesn't matter because in our biz, supply creates demand. Once department A in company 1 has a software system, department B wants one too. And then company 2. Then company 1 wants a program to synchronise A and B, then eventually migrate them both to C. By then, an army of support analysts, BAs and infrastructure people will be on the gravy train. The more work Wipro does this year, the more I'll have next year. The only other thing that works like that is hard drugs.
