The ruling class in the UK has always been very skilled at giving us just enough to prevent mass unrest. Most people (possibly to their credit) are quite content when they have enough food, a liveable home, schooling for kids, some entertainment and cheap escapism (booze, music, sport). The fact that they could have a much better quality of life or that the country is being looted largely escapes their attention.
That's where ownership of media by billionaires comes in, of course. They set the narrative. People like a simple, easy-to-understand story. If public services, employment, housing, health services are in short supply, it's the fault of the Polish joiner, the Syrian refugee, EU, woke students, distant wars...etc, everyone but the people actually running the country.
Maybe we will reach a tipping point this winter. When people can't afford heating, petrol, food, rent etc they won't care about the narrative, or where the "Overton Window" is located. They will just take to the streets.
