Gleaning is a process of the collection of leftover grains from the fields, gardens, grocers and other different sources.

Gleaning was the legal claim given to poor people during the eighteenth century who do not have a house or do have any land.

Gleaning was a method that has offered relief to the rural poor because leftovers crops were collected from fields that were already harvested or were not profitable to crop.

in the 1900s, the united states was still a largely agrarian society with a very fast growing industrial and manufactering sector.

the south of the country was the bread basket of the country with large farm lands making up a majority of the economy.

in the north and more specficially north-west, growing manufactering and export sector had made the united states into a powerful exporting country.

this peaked in the 50s and 60s when the united states became the largest economy in the world and the largest exporter.

today, the majority of the united states economy is made up of the services sector that includes banking, insurance, music, movies, hotels etc.
