as a leftist, i understand that these "socialism for the rich, capitalism for the poor" proposals are not just non-solutions, they are the core of the collapse of late capitalism. the unionized working class will be forced to pay for this wealth redistribution upwards from the proletariat working class to the bourgeois middle class. all leftists should oppose these policies. these are the class allegiances that mamdani maintains, due to his origins.
however, i don't think that mamdani is an anti-semite. rather, he may increasingly see leveraging growing anti-semitism as a means to grasp a hold on power, in the face of the growing reality that anti-semitism is becoming a populist issue amongst the bourgeois middle classes. we have seen this before, both in america and in europe, and we know how it ends.
leftists should oppose mamdani due to his not just petite bourgeois but in fact haute bourgeois economic proposals. they should also realize he is a potential front for something much darker that is brewing beneath him, without being the cause or the driver of it.
what he wants is to prevent downward class mobility in the children of the upper class, and he wants to do that by redistributing wealth from the working class upwards (by trickling the wealth up) rather than by redistributing from the bourgeois class to the working class. it might work, but only because people are voting for other things they are projecting on to him, and which he has no jurisdiction to influence. if the ballot question was correctly placed to new yorkers, they would reject this, but the real left is moribund and the right is retarded, creating deep ignorance on both sides.
winners: middle class, bourgeois bankers
losers: the proletariat working class
