Which policy in the US government led to harsh working conditions and monopolies in the 19th century?

The laissez-faire economic policy prevalent in the 19th century U.S. government allowed businesses to operate with minimal regulation and oversight. This hands-off approach facilitated the rise of monopolies, as powerful companies could dominate industries without significant competition or labor protections. Consequently, harsh working conditions emerged as employers prioritized profits over worker welfare, leading to exploitation, long hours, and unsafe environments. The lack of labor laws during this period exacerbated these issues, contributing to widespread social and economic inequality.
