Look at the conditions in Appalachia in the 1950s. Do people still live like that? NO. The type of poverty that caused a "War" to be declared no longer exists in America. The war has been won.
But, the politicians can't declare victory, because that would mean that many of them would be out of a job. Therefore, there will always be a war on poverty in the US.
When you define “poverty” as the lowest quintile of household incomes you will always have about 20% of households in poverty.
