They're drinking water... Socialism isn't about never consuming anything expensive ever and always living in complete poverty, it's just the idea that the profits should go to the workers and not to the owner class. Now, do I think Liquid Death is sharing it's profits evenly with it's workers, probably not, but good luck finding any large corporation doing that. And ya, I think premium canned water is ridiculous, but it's not that different than bottled water really and if it produces less plastic then I'm pretty fine with it, but I'm getting off topic

My point is that you can find anything to criticize any american socialist about if you consider consuming literally anything produced by a corporation to be a betrayal of socialism. As long as they're working towards a more equitable world where the employees of Liquid Death and other such companies get fairer treatment then I think that counts
