Class, Power and the Structural Dependence Thesis: Distributive Conflict in the UK, 1892–2018

Can political parties, social movements and governments influence market outcomes and shape the functioning of a capitalist economy? Is it possible for social democratic parties, and the labour movement in general, to promote a significant redistribution of income in favour of labour? According to proponents of the structural dependence thesis, the answer to both questions is negative, because the structural dependence of labour upon capital severely constrains feasible income distributions. This article provides a long-run analysis of the UK, which casts doubts on the structural dependence thesis. There is some evidence of a short-run profit-squeeze mechanism, but income shares are much more variable in the long-run than the structural dependence argument suggests, and the power resources available to social classes are among the key determinants of distributive outcomes.
