it stands to reason the more WC'ers around the lower the prices will be
now you may have 10 local WC'ers who are established and have "full" rounds
now add into that mix 5 new starters this year, they will need work, they might pick up the odd house thats been missed by the 10 established WC'er, they might go and canvas and pick up a few houses that they will offer a cheaper price ( cheaper because home owners are cutting back, concearned with the economy etc etc )
now one of these people who have gone for the cheaper price, they talk to others and say " ive found some1 great, he's just started up and charges be half what my last guy did ), the economy spirals downwards and more feel the pinch
add to the eqaution that you might have another 5 eastern europeans who will gladly earn 10 quid a hour ( keep in mind people on here mention earning 30 - 50 quid a hour )
i feel the WC'ing lark wil not get any richer, it can only go down, personally i dont have a issue with that per sa, as supply and demand will alter prices
