Migration actually brings in a net benefit of taxes, meaning more money to spend on services such as the health service than if they weren't there and, as it's a net benefit (they put in more than they take out), then that means an improvement in services is possible compared to if they weren't igrating to the UK.
As for whether the NHS is worse than during a pandemic? It probably isn't (I've had lots of personal experience of waiting in and around casualty the past 2-3 years) but attention is now focussed on it, without a 'reason' for government to hide behind. It's a shame that support has only extended to clapping on doorsteps, really.
I’m always a bit sceptical about net tax benefit stuff, especially when we’re around time of a pandemic where more people are needing things like doctors, hospitals etc and are probably unable working as much due to illness etc. It will depend on the tax take from migrants, over what period and how much people use public services. I’ve not seen any analysis for recent years
We need more working age people due to an aging population but I’ve said before how how much additional infrastructure (docs, schools, hospital beds, housing etc) do you need to deal with net 300, 400k, 500k per annum. All this takes years and we’ve never caught up.
In the last ten years the country has grown by something like 6% (3.5m+), during half that time it was going through austerity post financial crisis. We have ridiculously low productivity, an aging population and post pandemic where there is a far greater call on nhs, GPs etc. it’s a perfect shitstorm
This isn’t an immigration is bad post. we need a certain amount of net migration and many foreign workers are needed for nhs etc. Just that unless infrastructure keeps up with the increasing numbers there’s going to be strains everywhere in the system.
