The actual problem is inequality, but inequality in right/libertarian thought is supposed to be good. So they * reached for a more comfortable explanation involving 'the other': globalists!
* 'they' is a discourse smell, so I will cite some examples: Glenn Beck, Pat Buchanan, Alex Jones, Steve Bannon, Viktor Orban, etc.
It has been annoying, for almost two decades, to witness the success of anti-globalization propaganda.
Economic inequality surely is contributing to depression in young people. Exposure to wonderful people, products, opportunities and ideas from all around the globe is not.
