Andrew Young (L-R), former U.S. president Jimmy Carter, Lynda Bird Johnson, former U.S. President Bill Clinton, Oprah Winfrey, U.S. first lady Michelle Obama, Caroline Kennedy, and U.S. President Barack Obama attend ceremonies celebrating the 50th anniversary of the 1963 "March on Washington" at the Lincoln Memorial in Washington August 28, 2013. America is struggling to fully realize the vision that civil rights leader Martin Luther King described in his famous "I have a dream" speech 50 years ago, as the goal of economic security for all remains elusive, Obama said on Wednesday.
