Max Horkheimer warned that capitalism and fascism have strong interlinkages: "whoever is not willing to talk about capitalism should also keep quiet about fascism"
However, Slobodian notes that "[c]apitalism can be hard to find" in contemporary literature about fascism
reviewing a set of books about the alt-right, Slobodian observes that "[r]eferences to 'identity' outnumber 'capitalism' at a ratio of several dozen to one. The assumption seems to be that Far Right ideology [...] inhabits a space of culture detached from issues of production and distribution. This is startling given the fact that the radical Right's central issue is nonwhite immigration, an eminently economic issue with a vast specialized literature."
An alternate understanding would have it that the Far Right is a "mutant form" of neoliberalistm, "shedding certain features--like a commitment to multiliateral trade governance or the virtues of outsourcing--while doubling down on Social Darwinist principles of struggle in the market translated through hierarchical categories of race, nationality, and gender."
