Return of the guest worker:guest or servant?

Demands for temporary visas are increasing in the UK, but few are discussing the details of how such short-term visas are going to work. Alan Manning writes a nuanced account of the trade-offs involved. The worse the conditions under which the migrants are hired, the worse it is for the migrants, but probably the better it is for employers and their customers. Transient groups of workers will almost certainly be the poorest people in UK society, which becomes more unequal as a result.
