Yep. Cheaper workers. That's what was ****ing up the wages for many trades. Great if you want a cheap wall built but not so great if you've spent your life in a trade and found yourself priced out of the market because you're not prepared to live away from home and sleep ten to a room.
One of my neighbours has just gone back into the toshing game. He gave up a few years ago when he was expected to work 8 till 6 for £80 a day in London because the Eastern Europeans were doing it. Dunno what he's getting now but it must be worth his while. He's home by 5.00 most days.
Ive never noticed any reduction in wages of trades around here, ever.
