Communism worked great in practice, just look at places like Burkina Faso under Sankara, Cuba flourished when the colonizers got kicked out, USSR and China went from semi-feudal societies to world powers in a couple of decades, etc.

Just like a western imperialist, you point at how powerful and wealthy the ruling elites of your favorite regime are and completely gloss over the suffering they cause their people.

China is a nation of slaves, locked into factories fitted with suicide nets as though they were criminals. Russia's populace is being fed to a meat grinder solely because their president craves power and conquest. And that's the example you'd have the rest of humanity emulate? Here in America, even our homeless live in better conditions than that!

You're no better than those you hate—you're hardly even different from them, let alone better—and that is why no one wants to join you in the revolution you desire.

On the other hand, do you believe capitalism works well in practice?

Of course not. But you certainly aren't offering a better alternative. I might be down for an honest communism-ish economy—mandatory employee ownership of businesses, redistribution of wealth via wealth tax, that sort of thing—but I'm sure not buying what you're selling.
