Another world is not possible.
Too often I see "another world is possible" as an aspirational slogan used to get people to fantasize about quick changes, people rising up, lucky rolls of the historical dice etc. I don't believe in historical inevitability or historical progression through stages, but I do believe that our current world is an outgrowth of widespread basic beliefs that do not change quickly or easily. To make another world really possible, it has to finally become as inevitable as our current world is.
A lot of that has to do with having the courage to reject basic beliefs that inevitably lead to bad ends even if they temporarily can seem not that bad. If you believe in a state or in capitalism, your beliefs lead to all of the bad things happening now.
