None of what systems? Huh? I know you won't engage with the critical thinking it takes, but for the reader: capitalism is just the last few hundred years' new iteration of the domination that's been carried out by those with resources against/using those without/with less. The milquetoast liberal refrain "it will never work," "it's been tried" drfeatism is pathetic naivete at best, intentional psyop to breed nihilism and maintain the status quo at worst.
