Trying to look on the bright side, perhaps this policy will force employers to pay people proper wages. Of course,it's not guaranteed that this will address the shortage of workers, and it would not be an instant solution in any event. It will also mean that either farmers go out of business or consumers will have to pay significantly more than at present. That will be an annoyance for the reasonably comfortably off but a disaster for the growing number of people living hand to mouth.
It is also worrying that the care sector is warning of an escalation in staff shortages. I think wages would have to be significantly raised in order to attract people to what is a very demanding and responsible job, which is described - unfairly I think - as "low skill". The cost of residential care is already enormous so I wonder whether care companies will wish to continue in a market whose profits will be even more seriously squeezed. Likewise the hospitality industry.
Although I would like to be optimistic, I feel that little preparation and planning has been made to address these problems. If EU workers gradually withdrew from Britain perhaps it would not be such an issue but there are already reports of serious shortages of workers and I feel it is unlikely that these gaps can be filled with the degree of urgency that will be required.
On top of that, highly skilled EU workers, such as engineers, scientists, medical and nursing staff, technologists, etc, are reportedly feeling they are less welcome in Britain and are no longer considering taking up employment here - and some of those who had intended to stay are thinking of moving elsewhere.
Will all this really help Britain to "unleash its potential"?
