Things you hate? How can it be explained as capitalism if you won't say what it is.
You act like there was never a guy named Karl Marx who proved this stuff, and debunked many myths about the economy, like 150+ years ago. It isn't just a random thing like a superstition. In fact believing capitalism isnt responsible is almost a superstition.
Wages are flat while production has skyrocketed the last 50 years, a little longer than I've been alive. The system produces a few rich people at one end and a bunch of poor people at the other, that's what it is meant to do, it's what it does. It isn't just an economic system, its the state and media as well.
People aren't just blaming all their problems on capitalism like some petulant child. There are causes that are very clear and some more hidden, but its no secret and hasn't been for a pretty long time.
The USSR moved out of State Capitalism with the end of the NEP. It is technically correct that they had a State Capitalist economy, but they moved on to a traditional Socialist economy relatively early on.
In my opinion it has to come from a bottom up movement, that puts emphasis on the sort of types of organization a socialist movement ultimately aims for.
The Leninists tried to disconnect the means and the ends of the movement, using the tools of the bourgeoisie to try and build a new system, which failed.
Marxist-Leninists did not "disconnect means and ends." The goal of Marxism is liberation of the proletariat, the means of which being working towards Communism, a fully publicly owned, centrally planned world republic free of classes, the state, and money. Marxism-Leninism adds analysis of Imperialism, Capitalism as it spreads internationally (which was not developed yet in Marx's time), as well as strategic advancements like Democratic Centralism and the Right of Nations to Self-Determination.
Marx was not an Anarchist, he wanted full centralization and public ownership, not a horizontal network of Communes. Engels even argued against such a system in Anti-Dühring.
