I don’t buy the “media and rich elites brainwashed society” myth. It’s a modern take on “the Jewish money men caused all the problems” that was a frequent trope in the past.
British voted and got what they deserved, period. Now they need to elect new leaders with new ideas.
People sell themselves for as little as $500 in corruption money. Elites haven't reached their spot just by themselves, they rely on massive tree-like corruption networks, where the leader of each branch gets to benefit more the more people they have under them. In a given society you have a small percentage of people completely morally corrupted, a large majority who are just ignorant in every regard, and a handful of people who actually gives a damn - about anything.
