Which important woman of the 20th and 21st centuries is distinguished by her influence over everyday Americans?

Oh, dude, that's like asking me to pick my favorite slice of Pizza! But if I had to choose, I'd say Oprah Winfrey takes the cake. She's like the queen of daytime TV, inspiring millions with her wisdom and giving away cars like they're candy. Oprah's basically the fairy godmother of empowerment, making everyone feel like they can conquer the world one book club at a time.
