I am not sure that is quite right. There is a system of salary thresholds, of which £30,000 is one, but there are others. For example, there is a new entrant rate of £20,800; for NHS staff and teachers, the national pay scales are the relevant salary thresholds. To take the two examples you gave, butchery is one of the medium-skill occupations that we recommend should become eligible for non-EU migrants, but it is one of the lower-paid occupations. We do think that the sector needs to offer more. It is not terribly attractive work, particularly when one is talking about the big food-processing plants; I have visited one. That sector is, again, not paying wages that are competitive in the domestic labour market.
I do not think it is unreasonable to expect it to be able to compete for labour in a tight labour market. We want people to have high-quality jobs, which is partly about high wages but also about good terms and conditions. I do not feel that that sector is fully stepping up to the mark at the moment.
