There have always been poor. They have been called peasants, serfs, slaves, and worse. They were often born into their situations and kept there by a noble or tyrant class that truly did prosper off of them and tried to keep them tied to the land.
It is not often a place where a man starts life in a poor household and can rise to the highest offices in the same land through his own hard work, but America is such a place.
We offer public education, assistance with food, assistance with housing, assistance with medical and dental, clothes and other items are often donated and available at very low prices if one is willing. Poverty would have been ended if it were just about things. Poverty is more of a deficit of the soul than of the body. DUmmies complain that the forest blocks the growth of a tree.
