Let's try out democratic socialism instead of democratic capitalism, why not? I love America and my neighbors of all races and religions and creeds, let's make it great with socialism.
The real fantasy is believing capitalism will usher in a semblance of peace across this Earth, yes even for those brown and black people in the americas, Middle East, pacific islands, and Africa. I'm not so sure why you believe it's the only way to make it happen.
Do you think democratic socialism fundamentally, foundationally, has a stance on what is and isnt property, and who can or cannot own it, and what is or is not ownership of property, and what level of violence is or is not tolerable in defense of property? If socialism does have quantifiable stances on these things, is it not perfectly reasonable to suggest socialism makes an attempt to address the issue of the original post?
Democratic Capitalism says anyone can own property, anything and anyone can be property (slavery is state sponsored and is allowed within democratic capitalism), and it allows murder in defense of any property. Can a cop kill someone looting a grocery store? Do you believe such a thing be allowed fundamentally allowed in a democratic socialist economic system? Which system do you think would logically lead to a more peaceful planet—the status quo or democratic socialism?
