I'm not speaking in favor for the UK specifically because they're basically still a monarchy with a parliament that doesn't represent people proportionally, but the government is the enemy of non-government powerful entities and organizations as you illustrated with the Beatles example.

By having a democracy where people vote on issues, you're participating in government for your own interests. If everyone did that properly, the government would never hold the interest of corporations over the interests of individuals. The problem arises when not enough people vote or are educated on policies, so then corporations and vocal ideological minorities can simply use money or coercion to convince people. And in doing so they directly oppose democracy, and therefor government.
