Because politicians are not accountable to you and are paid for by lobbyists.

This is not a conspiracy theory. This is not a UK/US only problem. The EU nanny statism isn't a good thing nor is the loss of sovereignty associated with it.

But hey, the left right binary choice strawman made it so that people basically pushed for more gov power no matter what and now it's too late to stop the inertia.

The next time you need to vote against accumulation of power they'll scare you again with extremists, terrorists, drug dealers, children safety, disinformation (which is basically calling for suppression of freespeech and criminalization of wrongthink), etc.

If you're still labeling people as "disinformation spreaders" that are dangerous then you can't complain.
