Hey Karl, it seems that we have made similar observations of modern British youth, you and I.
But as regards who's going to be doing the work (and, believe me, the actual work will still be there) in ten years time, well, all I can say Mate is that you haven't been paying attention! As I've mentioned a couple of times already, it will be done by willing hands from Eastern Europe (after all, we're all good Europeans now, you know).
