I'm really not trying to be a dick, but uhh... Look around? The world is literally on fire and efforts to put it out or even to stop pouring more gas on it are put down at every turn by capitalists in the never ending pursuit of more money for it's own sake.
Let's start here: are you a capitalist? Do you own any actual capital? I don't mean your own house or car, that is personal property not private property or anything resembling the means of production.
I ask because many people consider themselves capitalist when really they are just workers who happen to own a bit of personal property, and they make themselves essentially useful pawns for actual capitalists.
And, if you're not an actual capitalist, why are you so pro capitalism?
