At present the question of state capacity is orthogonal to left-right divides. On some limited matters (e.g. management of a national health insurance system) the left embraces it, on others it is hostile. https://twitter.com/DanielDenvir/status/1353509062420389888
This isn't true of just the *left* left. It's true of left-of-center politics broadly. I come back to this thing I wrote a few years ago. No one on the broad left is particularly interested in how to fix our inadequate bureaucracies. https://democracyjournal.org/arguments/politics-is-failing-mass-transit/
I don't have a great explanation for this. Some of the current left has remnants of New Left-ish hostility to expertise. But also the radical conservative turn looms over everything, and forces a framing of everything as investment vs. disinvestment that isn't always right.

You all know this is my view already but I think we've got to resist the idea that we can solve our problems through a redistributive night watchman state that taxes billionaires, insurance companies, and the oil supermajors into oblivion and does basically nothing else
