Who is "we"? There is no "we". Capitalism exists because different people have conflicting desires and unequal abilities. Capitalism is just another word for natural selection. Any attempts to get rid of capitalism as the "default" state of interhuman relations, will have to be accompanied by massive amounts of force, because you cant fight human nature without force. And even then, the only people willing to invest force and suffering to end the natural state of things are people who would personally profit from ending it, otherwise they would have no motivation to lift a finger, let alone lose one fighting to end capitalism, which then makes the attempt to violently end capitalism just another, more brutish form of natural selection.
You can not somehow "out-smart" natural selection and evolution and make people live happily together ever after without anybody exploiting anybody else. Inequality is a fact of life. By forcibly ending capitalism, the most humane form of natural selection to date, you can merely make the endeavour more bloody again.
