There is a *tiny* bit of truth in the statement...
If you're a temp ansd your rate is say £6 an hour, and someone else comes in and is willing to do the same work for say £3.50 an hour (or whatever), who's going to get the job?

My brother had to recently leave the building trade after 20 odd years, because all the guys he did jobs for are taking on cheap labour instead.

They are some occassions where they are not exactly nicking jobs, just forcing out other people.
