Not sure how you justify last Labour govt “improving” our lives any differently than Tories (other than superficially). As I recall they conspired in the invasion of Iraq and helped wealth transfer upwards when they bailed out the banks. I come from a working class, council house background and my life hasn’t been improved by either Tories or Labour.

I used to work in secondary education. The period under Labour was horrendous: we had the various “National Strategies” which micromanaged how the curriculum was delivered. Cost billions and was a waste of time. They also introduced MATs and PFI which took schools further from democratic ownership and allowed a minority if schools to thrive at the expense of others. Worst of all, their right-wing approaches enabled Gove’s reforms a few years later that have turned schools into toxic hell-holes where everything is measured around exam passes.

My view of Labour (and I was a party member from the mid-1990s until very recently) is that it really is an enabler of neoliberal policies. Like the Democrats in US, they are simply the same party as the Tories and just wear different colours. Socialists stay in Labour because they live in hope things will be different.
