The problem I’ve been hearing about is how many Liberal parties across the West are fracturing into three factions:
1.) Educated, degree-holding professionals and political elites. Aka the Brahmin Left, purveyor of high-level, top-down global policies (like climate change); yet are not afraid to embrace corporatism.
2.) The declining traditional socially conservative working-class. Aka the traditional Left of the unions, localism, and worker’s rights.
3.) Students and Ethnic minorities. A newer, increasingly powerful, occasionally radical faction that must be constantly appeased via social programs, lest they simply don't vote- or that they storm the Establishment gates.
With globalization, educational inflation and mass migration, the first faction is counting on the third to replace the second. As the second faction feels increasingly marginalized and attacked by the other factions- it looks to, and accepts Conservative populism as a way out- MAGA and Brexit are symptoms of this. The left’s inability to accept these movements as essentially populist rebellions against a perceived Globalist order has only infuriated the working class even further, who may see things like the 2nd Brexit Referendum as being fundamentally undemocratic. Hence the Brexit party, which exists only essentially as a protest vote, and which sapped huge numbers of votes from Labour.
Furthermore, these factions also inevitably fight, have their own separate objectives- and so are unable to present an unified vision. So you have the first faction alleging the third faction is responsible for anti-semitism in Labour, Labour presenting a muddled mashy-feeling vision and none of it working against the singular resonance of ‘Get Brexit Done’.
