After the Second World War, in part due to the experience of the First World War, most of the participating states set up elaborate veterans' administrations. Within the United States, it was veterans groups, like the American Legion and Veterans of Foreign Wars organization, that pushed for and got the G.I. Bill enacted. These gave veterans access to free or subsidized education and health care. The newly educated GIs created a significant economic impact, and with the aid of VA loans were able to buy housing and establish themselves as part of a growing American middle class. The explosion of the suburbs created sufficient housing for veterans and their families.
