They succeeded in finding a causal link between austerity measures and increased mortality.
At the end of the paper they estimated that 120,000+ people have died as a result. Additionally: that the the rate of excess deaths was increasing year on year.
There is an issue with highlighting this;
For starters, many people are very likely to bury their heads in the sand:
* "How do you know that it's related to Austerity" (not reading the paper)
* "They would have died anyway"
* "The world is different from the time period it is modelled from" (it corrects for this by comparing also to other roughly equivalent economies)
* "The UK is different than other advanced economies!"
The other issue is that it sounds so insane and conspiratorial.
120,000 is a large number. It's approximately the size of Stratford upon Avon.
A follow up study puts the number now closer to 330,000, around the population of Coventry.
Somehow people will blame the NHS for not being efficient, though evidence to the contrary exists throughout its history, often being one of the most cost effective healthcare systems in operation; or that COVID is a contributing cause to these figures.
People are unwilling to hear this: This was a problem well before the pandemic.
