New face of China's soft power

Why are first ladies so important in the United States despite the fact that they are unpaid and have no official responsibilities? There are several reasons, but the most important reason is they are role models for other women in the United States.

Theodore Roosevelt called the White House the "bully pulpit", as he believed it was the perfect platform for promoting social causes and ideals and all the first ladies since "Lady Bird" Johnson in the 1960s have used the bully pulpit to advance social causes.

"Lady Bird" Johnson was an environmental pioneer. Pat Nixon promoted volunteerism. Betty Ford was an early proponent of women's rights. Rosalyn Carter an advocate for the rights of people with mental health problems. Nancy Reagan used her time to fight drug abuse. Barbara Bush promoted literacy in general, while Laura Bush focused her attention on childhood literacy. Hillary Clinton was a child advocate and author. Michelle Obama is currently leading a fight against childhood obesity, a problem of epidemic proportions in the US.
