After the International Brotherhood of Teamsters' US Convention 2036 concluded, attendees generally agreed they had nowhere to go or anything to do, so they might as well stick together. The Union was their only connection left, so they decided on solidarity rather than letting their energy and momentum going to the wind.
The Settlement was a political statement, one that needed no manifesto as news footage of the armies of now homeless and jobless people camping out in tents and vehicles in the environs of St. Louis shocked the public of United States of America.
