The only time Britain has been remotely socialist - post WWII - we got the NHS, welfare, legal aid, social housing and so on. It's neoliberalism that has led to corruption, authoritarian control and growing poverty and inequality.
Socialism has been tried over and over again for a hundred years across dozens of countries.
Every single time it ends the same way - poverty, corruption, authoritarian control, and eventually collapse. The only variation is how many people starve or get shot before it falls apart.
And every time the defenders crawl out with the same braindead excuse: “That wasn’t real socialism.”
At some point you have to accept that if it keeps failing in the exact same way, maybe the problem isn’t the execution. Maybe the idea itself is fucking retarded.
