Capitalism hardly encourages the opposite of cooperation. To the skeptical, negative thinker, perhaps. Capitalism requires cooperation, often on a grand scale. TBH, it also encourages competition, which ultimately brings out the best in people, the best product, etc. You make it sound like with capitalism it's one on one, with every person against every other person, and that's simply not the case.
If you want to claim that there are countless examples of how socialism works for people, then if you're being honest, there are an order of magnitude greater number of examples of how capitalism works for people.
Capitalism has lifted more people out of poverty than socialism, by far. In fact, it's done that for more people than all over economic system in the history of the planet, combined. (that's the math of it, but you'll deny it, no doubt.) Like any system, it has it's negative aspects, as does socialism (though apparently you'll never admit the latter is true.)
You really should take a step back and reevaluate the "why" of your being communist, and believing socialism is such a good system. And like I said in another post yesterday when you said you're poor; you're only poor because you want to be. Capitalism gives you an unlimited number of options to no longer be poor, but you've apparently refused to adopt any of them.
Yep, that's just my $0.02. And it is *my* $0.02, not everyone's, as socialism would have it.
