It has been 36 years since the assassination of the Rev. Martin Luther King Jr., the American civil rights leader. Since his death in April of 1968, a whole generation has grown up in a country that he and his movement changed forever - and for the better.
Many young people today cannot imagine that in their grand parents' lifetime many states had official policies that barred African-Americans from entering schools and other facilities paid for in part with their tax dollars.
Using the philosophy of non-violent protest developed by Henry David Thoreau and later practiced by Mahatma Gandhi, King and company changed America from a land where the color of one's skin mattered more that the content of a person's character.
But it it is not enough to remember King, although that would be better than treating today as just another holiday. His son, Martin Luther King III, said in 2002 that remembering is appropriate, but not celebration, because there are still too many people in need of food, decent shelter and training that would allow them to earn a living wage.
