But there is another America. This other America has a daily ugliness about it that transforms the buoyancy of hope into the fatigue of despair. In this other America, thousands and thousands of people, men in particular walk the streets in search for jobs that do not exist. In this other America, millions of people are forced to live in vermin-filled, distressing housing conditions where they do not have the privilege of having wall-to-wall carpeting, but all too often, they end up with wall-to-wall rats and roaches. Almost forty percent of the Negro families of America live in sub-standard housing conditions. In this other America, thousands of young people are deprived of an opportunity to get an adequate education. Every year thousands finish high school reading at a seventh, eighth and sometimes ninth grade level. Not because they're dumb, not because they don't have the native intelligence, but because the schools are so inadequate, so over-crowded, so devoid of quality, so segregated if you will, that the best in these minds can never come out. Probably the most critical problem in the other America is the economic problem. There are so many other people in the other America who can never make ends meet because their incomes are far too low if they have incomes, and their jobs are so devoid of quality. And so in this other America, unemployment is a reality and under-employment is a reality.
...And among black youth, it is in some communities as high as 40 and 45 percent. But the problem of unemployment is not the only problem. There is the problem of under-employment, and there are thousands and thousand, I would say millions of people in the negro community who are poverty stricken - not because they are not working but because they receive wages so low that they cannot begin to function in the main stream of the economic life of our nation. Most of the poverty stricken people of America are persons who are working every day and they end up getting part-time wages for full-time work. So the vast majority of negroes in America find themselves perishing on a lonely island of poverty in the midst of a vast ocean of material prosperity. This has caused a great deal of bitterness. It has caused a great deal of agony. It has caused ache and anguish. It has caused great despair, and we have seen the angered expressions of this despair and this bitterness in the violent rebellions that have taken place in cities all over our country."
Rev. Martin Luther King, Jr. (from "The Other America" March 14, 1968)
