Aye. Ultimately Corbyn has to find a way to win trust on the economy in particular. Some of the smaller policies can actually help with this - Rather than continue spunking £27bn and increasing every year on housing benefit, it actually makes sense to borrow some cash, and invest in housing (ideally social housing) so we can get that bill down long term. Likewise on keeping profit making services inside the public sector - financially alone it simply doesn’t make sense to sell off the Land Registry, Ordnance Survey etc when they contribute to the exchequer. The only reason to sell them is to get a one-off boost to make it look like the budget deficit is decreasing faster than it actually is.
Small beans perhaps in the grand scheme of a £780bn budget, but those are the kinds of seeds that might be able to sow a perception of competence and financial literacy if nurtured properly, particular if the economic costs of May’s chosen approach to Brexit can start to be emphasised too.
Even so, the whole thing is still difficult-difficult-lemon-difficult for not just Corbyn, but Labour as a whole to solve.
