There is good in Blair's essay in that he tries to shift focus onto big systemic challenges and not just personality battles and popular issues.
But it falls down for me on solutions and particularly on his theory of solutions. He says:
"Put policy first and politics last. So, you begin with the question: what is the right answer?"
This is the worst of New Labour's approach to politics. As if somehow there is simply a scientific, objective, values absent answer to everything we just need to find and implement.
This is almost never true. Evidence is contested. Outcomes are difficult to replicate and scale.
In economic and social policy, politics has to come first because you will always advocate for policy based on what you *believe* will work best. You must be upfront about your belief set and argue why it is best.
