What was known for sharing wealth ideas they were new in the US in the early 1900?

In the early 1900s, the concept of wealth sharing was prominently promoted by figures like Andrew Carnegie, who advocated for the "Gospel of Wealth." This philosophy suggested that the rich had a moral obligation to distribute their surplus wealth for the greater good of society, primarily through philanthropy. Carnegie and others believed that the wealthy should invest in public goods such as libraries, education, and cultural institutions, which would benefit society as a whole. This idea marked a shift in how wealth was perceived and utilized in the United States during that era.
