Has anyone noticed that the contractor's laborers on the PBS THIS OLD HOUSE (?) show seem to now be Latin American?

Only the business owner (the contractor) and the show hosts are gringos now. All the labor now seems to be non-gringo (at least in the recent past and what the camera's have shown). This was never the case before (as I recall). This may indicate just how many gringo construction laborers have been displaced by likely illegals.
