You seem to be making an idealistic argument (ie, lmao what are you saying, of people don’t have to suffer, we have the technology to stop that) whereas the person you’re responding to is making a descriptive claim about how the world currently is.
I agree completely, people don’t have to suffer. But that’s what the current world is built on. The suffering of the poor, the minorities, the illegal immigrants, visa slaves, sweatshop workers etc. Just because things doesn’t have to be this way doesn’t change the fact that things are this way and it doesn’t look like anything is going to change anytime soon.
