The attitudes of old Labour grandees toward long term benefit claimants would be considered ‘far right’ today. This something people like Frank Field who still had that vague connection to Old Labour actually understood.
The problem I have when talking to people of the ‘left’ generally, is that this idea of public services is ‘underfunded’ is repeated ad nausem. Firstly, it’s a manipulation based ‘real terms’ and the principle that running costs need to be matched to inflation is a faulty idea. If private sector companies operated like that, we’d be in trouble - they typically don’t.
In any case, if all the issues around pensions, welfare, the NHS, schooling (and so on) could be fixed with ‘x’ more funding, the government would just do that. Especially a Labour government. The reason they can’t just magically increase the funding is a) the cost of servicing debt increases and b) it creates a death trap for taxpayers of ever ending tax to fund public services.
