This paper builds on our earlier work, Meltzer and Richard (1981), on the size of government. How does the distribution of income changes as an economy grows? To answer this question we build a model of a labor economy in which consumers have diverse productivity. The government imposes a linear income tax which funds equal per capita redistribution. The tax rate is set in a single issue election in which the median productivity individual is decisive. Economic growth is the result of using a learning by doing technology, so higher taxes discourage labor causing the growth rate of the economy to fall. We consider two economic scenarios. First, in a developing economy the median voter chooses increasing taxes and increasing redistribution which causes the growth rate of the economy to recede from a high level as the economy matures. The increasing tax rate discourages labor and growth causing the distribution of pre-tax income to widen. Second, in a mature economy, the distribution of productivity can widen due to increased technological specialization. This causes voters to raise the equilibrium tax rate and reduce growth. The distribution of pre-tax income widens. We estimate the model using U.S. data from 1967 – 2011 with excellent results.
