Read the article by Glen Greenwald. Its long, but is worth reading.
Some quotes:
There is no single, unifying explanation for Brexit, Trumpism, or the growing extremism of various stripes throughout the West, but this sense of angry impotence — an inability to see any option other than smashing those responsible for their plight — is undoubtedly a major factor. As Bevins put it, supporters of Trump, Brexit, and other anti-establishment movements “are motivated not so much by whether they think the projects will actually work, but more by their desire to say FUCK YOU” to those they believe (with very good reason) have failed them.
After the market-venerating radicalism of Reagan and Thatcher, he said, “the center left” — Blair and Clinton and various European parties — “managed to regain political office but failed to reimagine the mission and purpose of social democracy, which became empty and obsolete.”
Just last year in the U.K., Labour members chose someone to lead Tony Blair’s party — the authentically left-wing Jeremy Corbyn — who could not have been more intensely despised and patronized by almost every leading light of the British media and political class. In the U.S., the joyful rejection by Trump voters of the collective wisdom of the conservative establishment evidenced the same contempt for elite consensus. The enthusiastic and sustained rallying, especially by young voters, against beloved-by-the-establishment Hillary Clinton in favor of a 74-year-old socialist taken seriously by almost no D.C. elites reflected the same dynamic.
