The question itself is problematic. What does it mean for it to be good? In a vacuum, no, multipolarity is not inherently good for the working class, and the evidence is forms of multipolarity that were bad for the working class. For multipolarity to be good, it must be inclusive of an anti-imperialist pole at minimum and an explicitly socialist pole must develop as well. Becker doesn't say China isn't that, but we all know that Russia isn't socialist so it's not enough for Russia to challenge the US. He's correct on this. The situation is terribly fraught right now. We are all waiting to see what BRICS announces in late August and we are all watching China without making predictions or value judgments hoping that we end up in the multipolar chess board we need. Until then, focus at home where you have power.

Listen to Becker's podcast and it becomes abundantly obvious that Shea is full of shit and acting in bad faith.
