The wealthy elite class draws most of its income by exploiting labor. This is done in a variety of ways but essentially most UK Billionaires make their money in private equity (over half.. same in US)... which really means they don't actually do much real labor.
Instead they need to extract wealth which often means creating a system where people's labor is exploited. To keep this system in check a control of the narrative is required so you can keep a lower class of workers "occupied" so they don't wise up to the reality of the situation.
One common theme is fear.. war on terror, axis of evil states.. some sort of plague..Y2K.. you can probably pull up many themes from the past.
The other theme is divide by culture.... you see this today with gender issues.. gay rights, etc. For example in most modern western states... the vast majority of citizens don't really care if people are gay .. they may or may not approve personally but honestly don't mind what people do with their private lives etc... So the narrative has to flipped and made more extreme ..it doesn't matter the issue it has to something that gets people riled up enough that they don't have much mental or emotion energy left to focus on the small group that is exploiting their labor. (So gender issue has to get extreme to the point where we talk about surgical altering children for example)
Notice both parties... somehow keep migrants flowing into Europe (and US).. Almost like pressure needs to be kept on keeping wages low.
In the US the federal reserve openly states this as the goal ..(https://canadiandimension.com/articles/view/us-federal-reser...). Little coverage is given to this and instead a strange spin is attached on how somehow the worker class will actually benefit by being paid less.
This is the same with survelliance bills. We must keep an eye on the worker class to make sure they don't organize and wise up to the reality of their situation.
My two cents
