In my opinion, the top three Progressive reforms that most improved American lives were the Women's Suffrage movement, the Food and Drug Act, and factory safety regulations.
Women’s Suffrage, enshrined in the 19th Amendment, gave women a voice in politics. This was a significant change because it made government more equitable and representative of the population.
The Food and Drug Act made food and medications safer, protecting consumers from harmful products and ensuring public health.
Factory safety regulations reduced workplace hazards, saving lives and improving working conditions for countless workers.
