The suffering is real but the link to migration is entirely made up.

Not enough GPs for the population? They’ve retired.

Too much traffic? More and more people own cars and the entire country outside cities is designed to require them.

No home? Councils were banned from building them in the 80s of course we don’t have enough housing.

giving an inch on the core anti migration argument is a mistake because it makes the action to actually fix these problems harder.
No action on migration can ever be enough because the racists want to kick every black person born here out, and the “legitimate concerns” crowd won’t see any improvement in their lives and will keep demanding bigger and bigger action alongside them.
