Party Bosses, is the right answer.
Party bosses were people who worked for a legislative machine. The objective of these political machines was to get explicit people chosen with the goal that they could control the legislative issues of the city.

They would enable outsiders to acquire occupations in return for their guarantee to decide in favor of an applicant formally with the political supervisor. This brought about a large number of migrants being constrained by political managers.
