Some economists, including Milton Friedman, have argued that Johnson's policies actually had a negative impact on the economy because of their interventionist nature, noting in a PBS interview that "the government sets out to eliminate poverty, it has a war on poverty, so-called "poverty" increases. It has a welfare program, and the welfare program leads to an expansion of problems. A general attitude develops that government isn't a very efficient way of doing things."[17] Adherents of this school of thought recommend that the best way to fight poverty is not through government spending but through economic growth.[18][19][20]
