Secular nationalism favored middle-class interests over class equality. [causal]
However, postwar secular nationalism, despite its radical promises, was ultimately a middle-class ideology that served the interests of its class. State capitalist measures, while moderately successful for a period, were unable to seriously address class inequalities and produce real economic change. Furthermore, in the 1970s many of these countries experienced crises that state capitalist methods were unable to resolve. The result was increased unemployment and growing class inequality—conditions that were only exacerbated with the introduction of neoliberal reforms.
