Obviously, a young family guy can't compete with those prices, but there are guys out there that can.
Take a guy that's just retired from the police, fire service or army with a good pension.
I know an ex policeman, he gets a pension of £1400 a month and has finished his mortgage, if he can earn an extra grand a month cleaning windows, he's sorted.
I bet for every 4 or 5 new starters, 1 will fit into this bracket, and he will under cut to get work, nothing we can do about it, He's within his rights.
