Economics. People in less affluent areas are being ignored, getting angry and casting votes away from those who only focus on issues where the most GDP is located. Urban centers with high tech buisiness and an educated population get the attention. Here in the states we are talking the deeply blue coasts with good jobs, fancy restaurants, Mcmansions shopping and flashy cars. People in economically depressed areas like the rust belt are making themselves heard by doing this. To a degree it needs to happen because we should not ignore the economic disparity. It’s not propaganda doing this, it’s the laborer who can’t feed their family after the only factory left in town closed. Nothing is mentioned about their situation but they hear all the PC stuff like who gets to use which bathroom. Not surprising Trump won. It’ll probably happen again too.
