Teachers often complain about agencies driving down wages. For agricultural work were there are large numbers of employees there are gang masters who decide who works and what they pay, after taking their cut. agenies probably modelled on these gang masters. The point is that many gang masters are now imigrants, so who gets the jobs. i agree about people being moved to jobs or jobs being moved to area of high unemployment, but neither seem to happen. one issue about moving for the unemployed is the lack of council or other suitable housing - putting that back could help solve it. But in many areas there is still a high level of unemployment. Surprising that often imigrant are housed in these areas as well - this makes little sense as there is already a shortage of employment - but housing is cheap.
