What a tangled mess the government have created! Net immigration of 745000 is on the surface too high. It is equivalent to the population of Nottingham! I say this from an environmental point of view. However the situation is much more complicated.
The UK has a massive jobs shortage (possibly in part caused by the NHS under funding of this government. The number of people claiming sickness benefit is over 2000000.). In part this is also caused by the lack of planning for an ageing population (which has grown year by year(joke!). Brexit also caused specific job shortages in certain industries like hospitality.
The lack of any coordination of this migration inevitably leads to disharmony in some areas where unfunded migrants are forced to create imbalances in societies (often at the lower end of a socio-economic scale. Language classes, which would have aided integration, have been closed due to lack of funding.
And whilst the Ministry of Education has had more ministers than most football teams have had managers! there has been no planning for the skills shortages that are now apparent. Whilst Sunak has made a lot of noise about planning for the future whilst evidence shows that there has not even been planning for yesterday!
So should migration be reduced? I believe a sensible answer is that immigration should be organised in a sustainable fashion. The present government and right wing press are more likely to stoke division and animosity though (however this explosion of immigration numbers has happened under a conservative for 13 years – and the Mail and the Express will have to work hard to find lawyers and civil servants to blame!).
Remember too that these migrants are allowed in with work visa’s and have not battled the English Channel. many are part of deals related to trade (India), war (Ukraine) and politics (Hong Kong). Will European countries offer help to Palestian refugees fleeing from Israeli genocide?
