Popularism is the abject rejection of reality. It relies on lies to make people feel like they have no power to challenge decisions and policy in order to keep someone in power / gain power.
That doesn't stop the underlying realities that it tries to sweep under the carpet.
The problem with current politics is that the Tories need it for Brexit and Labour need it to get into government.
Neither is interested in actually dealing with problems properly.
Everyone else is also trying to cope the tactics because they've seen them to be popular.
The irony is, that the majority of people don't want any of that shit. They simply want life to be better and keep just voting against the people who are making the greatest hash of it.
No one with any quality gets a look in with this type of politics because they are not wedded to the ideology enough, because they value the practical of doing shit more. They get squeezed out at low level local politics level for not sucking up enough.
