Final answer:
Early 20th-century Progressive reformers, predominantly middle-class, aimed to alleviate the abuses of capitalism through governmental regulation, seeking efficiency and stability. They pushed for reforms such as abolishing child labor, offering worker insurance, and regulating wages, differing from socialist and radical movements of the time by reaffirming capitalism.
Step-by-step explanation:
The group in the United States in the early twentieth century that pressed for reforms to correct the abuses of capitalist industrialization was known as the Progressive reformers. These were mostly middle-class women and men who prospered during the second Industrial Revolution, and rather than inciting a revolution, they aimed to reform capitalism to promote efficiency, stability, and to alleviate class conflicts. The Progressives' concern over industrial and labor regulation was driven by their fear of radical doctrines such as Socialism growing in the U.S., and they believed that a safe, fair, and efficient capitalism could be achieved through proper governmental interventions.
The movement pushed for a broad range of reforms, from abolishing child labor, providing worker insurance, mandating safe housing, preventing pollution, to regulating wages and work hours through labor unions. Also, organizations such as the National Child Labor Committee worked for federal legislation, but most Progressive initiatives took place at state and local levels to induce political changes.
