Doubt it will change, blame will always fall on others, just watch. The EU will still get the flak. Hell, the EU wanted to help the steel industry but the UK vetoed it because they buddied up to the Chinese.
With the current middle-aged and older generations, absolutely. But no matter which way the vote swung, their opinion wouldn't change - their mind has been irrecoverably damaged by decades of tabloid agendas, a false understanding of "the good old times", and witnessing industries/jobs disappear for reasons they don't fully understand.
But for the younger ones, while bitter, hopefully they can usher in new generations without the hubris and be better for it.
I attended a conference last week and one of the speakers was a researcher/anthropologist/trends analyst with a background in education. One takeaway she was happy to share was that for as much shit we give today's youth, we're actually raising a much more worldly and considerate generation that ever seen before - mostly thanks to the internet and social media. She called them "citizens of the world", and they're more willing to look at the bigger picture when decision making, and with a far lower priority on nationalism. It was a really hopeful and inspiring outlook.
