Yep, democratic socialism is ultimately a reformist position, which serves to extend the reign of capitalism by moderating it’s worse excesses. Capitalism cannot be reformed, any attempts to reform, democratize or socialize capitalism may yield short term improvements to quality of life of the working class, but if capitalism is not abolished, it will always reassert itself, and capitalism inevitably leads towards fascism. The New Deal prevented the US from sliding into fascism, so that’s ultimately a good thing, but it did not go far enough.
