Are we allowed to talk about the good things the last Labour government did yet? Because I am fairly certain that not doing so helps the Tories pretend to be a vehicle for positive change.
You frequently rake this up, and I don't think it makes anything like as much difference as you think.
I'll say now that I think the UK as a whole was substantially in a better place in that 97-10 period (or at least until the GFC happened). I personally look back on it as a good time, one of both social progression (as in, the diminishing of societal acceptance of bigotry) and economic contentment.
But there are millions in this country who didn't feel like they reaped the benefit during that time - or [and I think this is important] didn't perceive themselves to reap the benefits anything like as much as certain other sections. They ended up feeling left behind and a bit disenfranchised and disaffected; economically sure, as the McJobification continued (ZHC's, agency work & temp contracts, warehouse picking replacing 'proper jobs', etc) but also some socially (those that hold 'cultural traditionalism' dear). Whether their feelings were justified is another point*. The crucial part is that they felt left out of this 'boom' (which was itself largely funded by cheap consumer credit) that was taking place all around them.
They'd been being told by the RWM for years that the EU was holding the UK back, was imposing all manner of crazy rules and red tape, and letting in millions of Eastern Europeans undercutting their wages, stealing their jobs and clogging up the NHS and schools and roads (so that's why they couldn't get to see a GP, or had to wait a year for that operation, and couldn't get their kid into the best local school, etc). After 2014, this ramped up, with new actors entering the fray, financed by dubious sources, and the propaganda that all their problems were down to the EU (and, of course, to lefties and a 'metropolitan liberal elite' and unions and benefit scroungers). They pinned their hopes on Leaving the EU and then saw the politicians bicker about how this should be done, until the affable toff with mad hair came along with a simple message and the backing of those few MPs who'd always sounded serious about 'just getting Brexit done' without bothering with all that irrelevant nonsense about deals and the Customs Union and other crap that they didn't really understand.
So they voted for him, and he 'got Brexit done' and although experts (who needs experts, eh?) warned of problems, they believed the Tories and the RWM telling them that these were just trying to steal Brexit from them and cause problems like sore losers. Their social media echo chambers backed all this up, so it must be true.
I appreciate I've gone off on several tangents that I really didn't mean to, so apologies.
But my point is that a lot of these people didn't see the 97-10 Labour government in the same positive light that you and others do. Not because they're lefties who felt they were too right-wing and wasted the opportunity to reverse much of the damage to society and widening wealth gap that the previous Tory governments had inflicted, but because they believed that the benefits that that Labour government brought in hadn't reached them.
* I don't think they were, really, but the consumerist culture and the glamourisation of 'celebrity' and wealth, with advertising delivering a message of the dark side of aspiration, which is basically: you're only a success if you can have all this shiny stuff and a if you can't afford it, you're a failure. Look, even these no-mark reality TV wankers can have nice things, created a false reality.
