What is tediously bizarre is when posters go on about how great Blairism was, yet don't comprehend that changes that do not last, no matter how good at the time, are by their very nature superficial, because they're not rooted in a substantial power shift and consequently wither with the political cycle.
Perhaps one generation benefits? No more.
After the 2008 crash and then the 2010 election all that Blairite progress you bleat about turned to dust, because Blair did not tackle the root causes of the problems, the power imbalances in our society, consequently, when the political mood changed what he did was blown away.
I retired with a nice house, mortgage paid, final salary pension scheme! Life's good for us post war baby boomers! God bless Clement Attlee and Harold Wilson!
And they did........For a bit.
There's an important change that you seem to have completely overlooked.
Blair reset the political landscape in this country to where the majority of the electorate hold left of centre views.
They know it's achievable, and they know it works with capable people in charge.
Even looking at Johnson's "landslide" victory, the anti-Tory, progressive vote was bigger share of the electorate.
The biggest mistake Labour (more specifically the unions) ever made was appointing Ed Milliband instead of David. If David was appointed (as he should have been based on the democratic vote) there would have been another decade of Labour rule.
But by going down the hard left route of Ed and Corbyn, it allowed 12 years of Tory rule, no wonder they ripped up all of Blair's good work, they didn't have a viable opposition for 12 years!
Even if Blair had been as radical as you seem to have wanted, 12 years is plenty of time to completely rip apart anything he did.
The difference with Attlee and Wilson is, while they might have made drastic changes in a short time, they were just blips where people wanted a change from the Tories, but quickly went back to them after one term.
Whereas they may have effected bigger structural changes like the NHS and better pensions, they didn't shift the political positions of the general public in the same way.
With Labour's first left of centre leader since Blair, they look on course for victory again. That wouldn't have happened without him.
Hopefully if Starmer gets in to power, the last 12 years will be a sobering lesson for Labour that things can get better, and stay better, if they stick to the strategies and policies that can effect tangible change in people's lives, instead of pie in the sky wishful thinking.
