What are the roadblocks? It's hard to tell in the general case and it's still an open research subject in the empirical literature [1]; but for the specific case of labor inequality, there is consistent evidence that race differences in access to networks is one key roadblock --especially in the high-tech sector, where hiring 'through the vine' is common and encouraged [ibid, pp.15-16].
