Final answer:
At the start of the 20th century, diverse reformers called for more government intervention in the economy to address the negative impacts of industrialization like unsafe labor conditions and corruption. Progressives sought regulation to balance capitalism's excesses, while some worried this might edge towards socialism. The period ushered in significant reforms and the notion of an interventionist government became more accepted.
Step-by-step explanation:
By the turn of the twentieth century, reformers from different social classes were arguing for increased government intervention into the economy due to the social issues spawned by rapid industrialization and urbanization, like unemployment, dangerous working conditions, and political corruption. Middle-class Progressives sought to reform capitalism to prevent the spread of radical doctrines, such as Socialism, through government regulation of industry and the creation of welfare programs. The working class, through unionization and political engagement, demanded improved labor conditions and wages. This activist spirit was especially evident after World War I, where worker's income and expectations rose, perpetuating the push for reforms and increased intervention.
Skeptics of the Progressive movement feared that growing government power could unintentionally lead to a takeover of private businesses and encroach on the principles of private property, potentially becoming a step toward Socialism.
In response to complex social challenges, Progressive Era reforms manifested in trailblazing legislation at both state and federal levels, including the Sherman and Clayton Acts to regulate trusts and the creation of safety laws such as the Meat Inspection Act and the Pure Food and Drug Act, indicating the shift towards a more interventionist government.
