I have to agree with A & C and M.Mouse - it is simply supply and demand. Skilled building tradesmen are in short supply, on the other habnd there is a queue around the block for people wanting pilot jobs.
I also think it makes a refreshing change too see some genuine workers get a decent pay rate, at least they are doing something useful unlike most of the jobs you see advertised in the Guardian for 40 K
(Sure Start programme manager - Our Programme Managers will: - Have a proven track record of working with disadvantaged, multi-ethnic communities and an understanding of the needs of parents and children and community dynamics.
Not quite sure what community dynamics are?)
