Step-by-step explanation:
The reason why Theodore Roosevelt would be your answer is because he is the one that made the political program called "new nationalism." The reason why he made this political program was because he wanted to increase the welfare of the people that were less fortunate. Also, he wanted to have more social justice in the country because not everyone had a fair chance of social justice, and he wanted to fix that for them.
To increase welfare for the people that were less fortunate, he made national parks. The national parks gave a chance for people to enjoy a beautiful place and get their minds off of the bad things, and this caused the welfare of people to rise. National parks made people happier, and that's was Roosevelt was trying to accomplish. He also wanted to make sure that the U.S doesn't waste any valuable resources since the U.S was loosing a lot of resources that were very valuable and could help in the long run. Since he became president, he focused on saving important resources in the United States, and conserving those resources made the U.S economy better.
