Only if you limit “material interests” to the realm of capital. As materialists, we only deal with material interests, and those interests include the realm of social interests.

But I can think of historical examples too. During the Minneapolis uprising of 1934, the Teamsters shut down all trucking within the city that attempted to ship goods without the truckers union. One of the groups that emerged was petty agricultural producers that trucked their own agricultural goods to markets. The Teamsters gave these petty producers passes to truck their goods, which while keeping the food supply for the city available so that people wouldn’t starve, it also split these petty producers from the reactionary forces. I can think of a more recent example in Seattle with the campaign to pass a $15 minimum wage. small restaurant owners were allowed a few years to implement those changes whereas other cities which required an across the board implementation for small businesses as well as large ones, the campaigns failed or were quickly rolled back. And no, neither of those movements were revolutionary (though the teamsters rebellion was pretty spicy) but they were progress for workers that was only successful by splitting the petty bourg by making concessions to their material interests.

And maybe this is where we diverge as communists, as I don’t see a road to actual communism that comes from an uncompromising adherence to the maximum program. Its politics all the way down.

My point in the post above is more directed toward the creation of a socialist material interest that supercedes capitalist material interests, but I can support both perspectives given the right historical circumstances and a powerful materialist dialectic
