What bit is untrue?
Funding for the NHS in real terms increased between 2000-2010 and led to it being ranked the best in the world. Real term funding fell, capital investment funds were limited & poor workforce planning over the next 14 years led to it's current state. A deliberate and calculated choice.
Investment in housing, particularly affordable social housing, was deliberately restricted by government policy. Forcing councils to sell off housing stock and limiting their ability to reinvest the proceeds in new stock has been a disaster for working people.
At the last census, there were over a million uninhabited dwellings in England & Wales.
GDP per head in the UK 25 years ago was $28,762.1, in 2021 it was $46,869.8
So ask yourself where's the money going? All we've done since Thatcher is assist in moving public wealth and assets into private hands, pay for the economic crashes caused by a renegade international banking cartel.
But sure, it's all because of immigration and managers at the nhs.
