We have serious shortages of workers in a number of fields, including care, health, hospitality, teaching, the prison and probation services and many others. The situation has become considerably worse post Brexit. To say we have no space in those circumstances is just absurd. Not only do we desperately need immigration to fill all those vacancies, we need all the tax and spending leading to economic growth that the people concerned would bring to us.
But if our population were to stabilise or decrease, we would not need more and more healthcare, hospitality, prison guards, teachers and so on. The shortages are because we already have more people living here than we have supply of these services. Bringing in millions more then drives up the demand for these services and everything else even more. Can you not see it’s an never ending spiral of bring in more people to meet demand, which then increases demand in other areas, so we bring in more people for those areas, which then…
This cycle of ever meeting increasing demand has nothing to do with actual room/over population versus the landmass. The more people that live here, the more health workers (and so on) we will need and when we fill those shortages and those people will need more bin men, construction workers to build houses and roads, and teachers for their kids..which in turn creates more demand for what they do…and it never ends.
Youre stuck in the old grow or die mentality, we have to learn how to right size people vs professions and resources without relying on constant population imports to do it.
