Poverty has been dropping rapidly worldwide
And even in the USA. If you look at the poor in 1972 and compare them to the poor in 2021 there is a startling difference -- the poor of today would be considered lower middle class in 1972.
The Democrats have moved the goalposts to keep having a "poor" votebank. But the poor of today have no food fears, they have transportation, entertainment etc. that a middle-class person in 1972 would only dream of.
