I skimmed it, but you hadn't made any argument with factual information. There's nothing in that video that would refute the facts I mentioned otherwise you might have mentioned it. As a result my point stands.

Here's another article where they explain some 20% of east germany fled to west germany. I would assert this is because they didn't like how the country was being run. This was a gradual process.

By many accounts it did outperform capitalism. There were no homeless in East Germany, for example.

I am sure there are some benefits to socialism, that's why I suggest a blend of capitalism and socialism. However I would point out that under the extreme socialism you are advocating, undesirable people have a tendency to to be lined up and shot. I'm quite certain you aren't sitting on a gold mine of examples where mentally ill people are wondrously cured and sent back to work under socialist regimes for example.

Both systems are bad in the extreme.
