No, I'm really not. The capitalist model is the only one which gives everyone a fair chance at pursuing what they really want to do in life and make a success of themselves. That can't happen in socialist states, because if there is a doctor shortage for example, then we need to start forcing more citizens to become doctors whether they want to or not (Welcome to central planning).
I don't know where you get these misconceptions that bankers, CEOs, etc do nothing besides sit around in their office all day and earn big paychecks by playing Candy Crush. Nor do I remember reading many rags to riches stories involving Cubans or Soviet citizens in their former countries. Do you know anyone who has actually lived under those conditions at some point in their lives? I do, and 100% of them risked their lives to escape it for a reason. You really ought to find some and talk to them. Not many South Floridians are gathering up on rafts and trying to paddle their way into Cuba.
You keep bringing up these ancient civilizations. Who were they, and where did they exist? I think what you're really dreaming about is the socialist utopia...everyone continues to show up for work without getting a paycheck in return, and they do it for their fellow man. That simply isn't the way of the world. Hell, even in the wild...when a lion makes a kill, he doesn't go around and share it with every other carnivore species in the jungle. It's survival of the fittest.
And you STILL have not answered my question, because you it shatters your vision. But I'll ask again: we suddenly live in a socialist state, and I've decided I just don't feel like working. My reasons for doing so are irrelevant. So why should I work if you're going to pay me for not working? That's when your model begins to unravel.
