What were some ways political machines hurt cities?

"People without ability or experience became officials" is some way political machines hurt cities.

Explanation:

A political machine is a collective where an influential leader or small group commands the resources of a supporter and business community that earns incentives for their actions. This success is based on the manager or group's ability to get out the vote on election day for their representatives.

In the late 19th century, many machines emerged throughout towns to serve U.S. immigrants who regarded machines as a means for political conquest. Often, political patronage may involve exchanging money for political assistance.
