But @anniehm if these low paying jobs need doing, they need doing. They will still be 'subsidised' even if a Brit does them. What difference does it make?
Also, I disagree that a person who comes from abroad to work in a farm will not be a net contributor to the uk: their education will have been paid for by their country of origin and unless they have children in school in the uk and have medical conditions which they most likely don't, their earning 30k minimum before they are considered good value doesn't apply.
Of course the whole idea of saying that people are only of any use to society if they earn more than £30k is also a bit dangerous, in that to some politicians, that is precisely why the poor don't deserve investment in their free health service and education. The rich will have their private alternative education and healthcare, and as far as they are concerned the rest can make do with shit services, since after all they're not working hard enough. So be careful what you wish for.
As for tax credits, they are just a form of tax distribution, and are only in the form of a payout so that higher paid people don't get this tax cut as well. Unlike a rise in personal tax free allowance, which they also do benefit from. And they are not going to stop. I don't think you would get them, as a single person picking fruit, would you?
Some jobs suit some people more than others at different point in their lives too. For a young immigrant, picking fruits abroad is an experience as well as a job, whereas for a Brit it might be more thoroughly painful. It's not like it has much potential for advancement either.
These jobs are not the kind that are going to be suitable fir someone in a formerly industrial area who wants to regain their dignity, if that is what the problem has been all along. (I'm not saying it has.)
Why are we hell-bent on having British people do low-skilled work that they don't want to do, and rejoicing that there will be more competition for better jobs?
I don't personally mind, but it doesn't seem logical to me.
It's just a measure to lower overall numbers, really.
Because wages are not going to rise, IMO. We as a society prove everyday that we don't value expensive, ethical products, and are not prepared to pay more for anything if we can help it.
If the rule is not retrospective (seems it isn't, but are we sure?) then I agree the personal distress stories are only those of couples who can't bring their other half over. Which is still cruel and ridiculous.
