> You talk about other systems that end in autocracy, and/or misery but capitalism does too.

No it doesn't, that's crazy. The United States is the longest continuous democracy in the entire world.

> The answer ultimately lies in regulations, and making economic equality the top priority.

No, the richest and most powerful countries with the highest median quality of life are the ones that prioritize growth, not equality. Prioritizing equality gets you the Soviet Union. Prioritizing growth gets you the United States.

> Greed is just another addiction, no different than heroin

The difference is that greed, when channeled through capitalism, creates value for everyone. Jeff Bezos wasn't an altruist when he founded Amazon, but the result is that everyone in the United States can have just about anything they want delivered to their door in a couple of days for free. Steve Jobs was a greedy, rapacious capitalist, but he gave us the iPhone. Etc.
