Completely agree.
Apart from a minority of comfortable gin-soaked shire Tories who see Brexit as the fruition of their tin-soldiers-in-the-celler Churchill cosplay fantasies, Brexit was a semi-conscious reaction against austerity. "Take Back Control" - nothing could have been better crafted to resonate with the people you describe above.
There were two recessions really - the first, shorter term one, caused by the financial meltdown; and the second, far more prolonged, devastating, and vicious one, cynically imposed by the Tories (and to some extent Lib Dems), based on pretext of the first.
Unlike the United States, Canada, China, Japan, Australia et al, which (at least on paper) have recovered nicely after the obvious appropriate response of fiscal and monetary stimulus, the Eurozone and especially Britain defied all economic wisdom and the experience of the previous Great Depression by cutting the legs out from under their economies at the moment of greatest weakness. The results speak for the themselves.
Brexit was the inevitable but predictably unanticipated backlash against an especially callous and venal ruling class (and its useful idiots, self-proclaimed "Centrist" Panglossian technocratic liberals), which, with all the deranged confidence that British public schooling uniquely instills, assumed that destroying entire generations through half-baked debating society positions like Universal Credit in order to lower its own tax rates would be all just a bit of a lark, and that somebody else would be made to bear responsibility, or suffer consequences.
I don't doubt the impact of the recession on forging the mindset we have today, but surely the response to it rests on the ease with which you (both the individual and the government) can blame AN Other. In Japan and China, immigration is very low, so that's off the table. Canada and Australia have huge natural resource based economies that have enabled them to weather the recession (indeed, I don't think Australia even had a recession did they?). The United States has immigration with a more diversified economy so are in a similar position to us.
As it is in Europe, as the chart below shows, government spending as a proportion of GDP has been falling in recent years, but is still above pre-recession levels, so the idea that there has been mass austerity, governments cut to the bone and so on isn't really supported by the facts.
I posted a few weeks ago about our propensity to believe problems still exist, even when they've been largely solved, and I do wonder if that isn't the case in the reaction of some to the aftermath of the recession. I've no doubt there has been hardship and difficulties for many, but whether you compare the hardship seen in Britain with hardships both in many other places in the world and that Britain itself has endured in the past century, then I do wonder if a bit of perspective is needed. I mean the world adapted to this recession infinitely better than it did the Depression.
