The Progressive Era (1890s-1920s) was a time when people worked hard to fix the problems created by money inequality. Here are some important changes that happened during this time:

1. Income Tax:

   • In 1913, the 16th Amendment created a federal income tax. By 1916, this tax helped the government earn around $1 billion. This extra money allowed the government to start more social programs to help people in need.

2. Regulating Businesses:

   • The Interstate Commerce Commission was started in 1887 to control the prices of railroads. This was important because high prices hurt workers. Then, in 1914, the Federal Trade Commission (FTC) was formed to stop unfair business practices from happening.

3. Labor Rights:

   • The Fair Labor Standards Act, passed in 1938, set rules for minimum wage and maximum work hours. This was the beginning of better rights for workers. In 1914, around 40% of American workers were making less than $2,000 a year. This showed that changes were needed.

4. Helping the Needy:

   • Settlement houses were opened in cities to provide services and education for poor people. By 1920, more than 400 of these houses were helping communities.

5. Women's Right to Vote:

   • The 19th Amendment, passed in 1920, gave women the right to vote. This was a big deal because it allowed women to have a say in their government and the economy. By 1920, women were spending about $21 billion as consumers.

These changes worked together to help reduce the gap between the rich and the poor, making society fairer for everyone.
