If you look at the detail though, the large increase in net migration is specifically driven by work and study visas (mainly health care in relation to work), not so called randoms who become a burden. I have said this before, but the main issue with immigration is the lack of accurate information disseminated and also politicians unwillingness to talk about it honestly. Net migration is not being driven by asylum numbers or people coming to the UK for humanitarian reasons, it is being driven by students and workers, and most importantly Non-EU. You do also have to link this to brexit, EU net migration is down, but all we have essentially done is replace these numbers with people from outside the EU.
If people do really want to reduce net migration, you have to be fundamentally honest about the reasons people are coming here and the implications for the UK if we reduce the numbers.
1) International students. If we reduce the numbers that obviously has a negative effect on UK Universities and the reduction in funding effectively kills a large number of them, taking thousands of jobs with it.
2) Workers, specifically in sectors such as health and social care. This is an economic and societal problem, people live longer and there are more of us, we need more hospitals, more plans for longer term healthcare for chronic conditions, more residential beds, more community/place based care, more mental health services. We simply do not have enough money to fund all of this or enough UK workers to cover the sectors. If we want to reduce our reliance on foreign workers then we need huge investment and a massive overhaul of the NHS/Local authority budgets, healthcare training (including better public sector pay etc.). This isn't going to happen so we need foreign workers or the system becomes untenable.
Immigration is such a complex issue but politicians and the media have for decades reduced it to a simplistic (and untrue) narrative of people coming here to take "our jobs" and drain "our services". The reality is that the people that really drain services are far more likely to be British, unemployed and suffer from chronic healthcare conditions, usually caused by class inequality.
