People should do what they want, not what you want, or any party or "glorious" leader. Trade created our world. As a certain P. N Whitehead said, men have resolved their differences through two means: force or commerce. What he forgot to add is that those who sucked at commerce wanted to control those who didn't by means of force, as the OP suggests.
Capitalism boils down with the right to private property and the right to use your property as you see fit. If you don't believe in it, go start your little socialist utopia wherever you want from my part. Just do it on your own dime.
In any way, it always amuses me to see people who grew up reaping all the benefits of capitalism condemn it in favor of socialism. Socialism used to say 150 years ago that the problem of production has been solved and all that remained was the problem of distribution. Tell me, how many advancements in production have happened since then? Socialism has concepts which are sheer nonsense but which for some reason are very catchy at first glance. Like democratic control of the means of production. Let's say I start a firm and devote my time and money in developing a product which becomes a success and can't keep up with contracts. I need to hire two more people to help in production. According to socialist principles they now have a say in production, "democratically" they can vote to produce whatever, even if they have no f clue about what they are doing and are mere;y doing physical labor, even if it was not their ideas, time, will and money which developed the business (had I lost my money or went bankrupt as MOST business endeavors do, would potential workers compensate my loss ? -- the workers want freerolls). If I invented the iPhone and the workers wanted to build 3310 because it has been successful in the past, I should just accept their decision as they are more. And don't get me started on dialectic materialism et al.
And even if you assume the problem of production can be solved, let's say robots, the problem of distribution is unsolvable top down or through voting or whatever. The solution for distribution is simple: money and its free circulation.
PS. All the people commenting are most likely capitalists. The problem is they don't know what socialism and capitalism are exactly and are muddleheaded.
