That's liberal as an adjective, not liberalism in its political definition. As a socialist I don't have a liberal party in my country that I can support. They think capitalism will be fixed if there are no disparities in how people are distributed within it. It's like thinking equal black and white slave owners in the Antebellum south would have fixed the economic arrangement of slavery.

I don't think liberal approaches are just unfavorable, I see how they perpetuate the problems they're invoked to address. We've seen nothing but wealth inequality rise as the latest liberal economic consensus came in to effect in the 70s. That economic stratification is what creates these problems, because you have ascriptive taxonomical hierarchies like race that develop out of economic relations like that.
