While tax reforms implemented under Democrat administrations, in particular the EITC reforms in the 1990s and the ARRA in 2009, had an equalizing effect at the lower half of the distribution, the disequalizing effects of Republican reforms are due to tax cuts for high-income families. As a consequence of partisan politics, overall policy effects almost cancel out over the whole time period.
