It's quite amazing to see you write about bureaucrats and regulators will not bring growth when the very paragraph above you set out how bad the Labour govt is doing in terms of growth etc when they've been getting rid of a load of them, so we can safely say getting rid of them doesn't bring growth either.
And while I agree with you about infrastructure projects being the better route forward (and I have stated how I think Labour cutting back on them was the wrong thing to do) I don't think just getting rid of public sector workers helps, as I've pointed out before. As for regulators, some of those are absolutely necessary because people and businesses, especially those in the private sector with a profit motive, will do stuff that is hugely detrimental to society in exchange for themselves making a fast buck. 2008 largely came about because of a lack of regulation.
Reeves is facing criticism but she's doing things that a supposedly 'competent' chancellor should do. We haven't seen a Truss like reaction because she's toeing the line and doing things like keeping the fiscal rules and cutting spending. Hence all the going back on promises and doing very un-Labourlike things like welfare, benefits and job cuts. Yet the economy continues to be in the shit, That's not because of her personally being a bad chancellor. It's because that's what those policies inevitably lead to.
But any policies other than that and the markets etc. go into meltdown because it's different and they don't like it. So you're buggered either way. Don't be thinking that the economy is based on sensible, pragmatic practice. It's not. It's largely based on vibes. Like a herd of cattle, if one gets spooked and runs, the ones next to it join in as well and so on until you've got a stampede running off a cliff for no real reason.
