Look at the reaction on a forum like this which represents the upper middle class business-oriented citizen towards the societal impact of tech. Globalism is seen as an opportunity here, not a threat. Politicians, media, academia and business have told millions of people that things are great, but they are the problem -- they lack education, skills, wherewithal and have expectations for prosperity that are misaligned with reality.
So they lash out. They think to themselves "If some douche from the Bank of England or the Conservatives doesn't like this, that's good enough for me." That's democracy -- it's a messy business.
Is that a "good" reaction? History will judge. Depending on your POV, the crowd is either wise or rabble. But -- the critique that democracy is somehow broken is an incredible leap of ignorance. We (speaking from the US perspective) have been offered a sham of a democracy that isn't meeting the needs of many. We're very fortunate that we live in an age where peaceful democratic revolution results in a bad day/weeks for stocks. A hundred years ago, you'd have mobs in the streets and soldiers with bayonets shooting into crowds.
If you don't have that resource or power, change for change's sake is rational.
Put another way - when you know your leaders are taking you in the wrong direction, then a random alternative is a rational choice if it is the only other option.
Look at the map. London wanted in. Scotland wanted in. The rest of the country is dissatisfied with their state and want out. Look at the US map and you see similar things.
You can call the populace stupid and ignorant, but by doing so you're displaying your own form of ignorance. Lots of facts and figures and economic models can be used to say that everything is just peachy, but the ground truth tells a different story.
