Agree with all of that, the issue I identified is one he signally failed to address - as did Burnham in his reply or indeed Milburn in his re-emergence yesterday.
Simply put the problem is our current welfare spending is unaffordable now and cannot continue.
At the risk of stating the bloody obvious it's a very very difficult problem for which there are no easy fixes. If you reasonably assume that borrowing simply to afford welfare spending is unsustainable and undesirable then it strikes me there two routes we can go down:
1. Simply reduce a variety of payments
Because I disagree with you about the degree to which it's simply a misdiagnosis crisis etc and I think it's more complex than that, I think this approach would have significant human and economic costs. Even if we took a callous "let the bodies pile up" approach, the chaos it would cause would balloon costs in other parts of the government's budgets I suspect.
2. Invest in programmes to reduce the number of people needing benefits in the first place
This second one gives us a chicken and egg dilemma, to invest we need a strong enough economy but to get a stronger economy we need as many people as practically possible to be productive in the economy. So what breaks us out of that downward spiral ?
Even with very credible plans with defendable projections about the impact it could have mid to long term on gdp/deficits etc the markets would charge very high premiums to support this, if at all. Meanwhile we have a situation where between 2011 and 2019 the wealth of the top 10% grew x 70 more than that of the average person! Despite the narratives we are in fact a very wealthy country it's just that much of the wealth is hopelessly concentrated and unproductive.
So to me there really is no other rational option than to start addressing the huge levels of inequality through tax reform. As I've already suggested, I believe the UK super rich are pretty rubbish as useful economic actors so they need to become more productive in the economy and this would be one way to make them much more productive and generate much needed investment in a country that has been systemically under invested in for decades now.
Labour seems pretty reluctant to go there but has anyone really got a better plan?
Blair hasn't, Milburn hasn't, I suspect Burnham hasn't. I'm not suggesting that it's easy either politically or technically but what other options exist?
The irony is that, strip away his ideology (his famed pragmatism I tend to think was something of a misdirection) and once upon a time Blair was a sufficiently good politician and communicator that he might have been able to carry the national debate needed.
