What did progressives work against monopolies?

Progressives worked against monopolies in the late 19th and early 20th centuries by advocating for antitrust laws and regulations aimed at promoting competition and protecting consumers. They believed that monopolies concentrated power and wealth in the hands of a few, stifling economic opportunity and innovation. Key legislative efforts included the Sherman Antitrust Act of 1890 and the Clayton Antitrust Act of 1914, which aimed to break up large corporate trusts and prevent anti-competitive practices. Progressives also sought to raise public awareness about the negative impacts of monopolistic practices on society and the economy.
