From Dr. King’s last public speech (“I’ve Been to the Mountaintop“) in Memphis, TN on April 3, 1968:
We have an annual income of more than thirty billion dollars a year, which is more than all of the exports of the United States, and more than the national budget of Canada. Did you know that? That’s power right there, if we know how to pool it.
We don’t have to argue with anybody. We don’t have to curse and go around acting bad with our words. We don’t need any bricks and bottles. We don’t need any Molotov cocktails. We just need to go around to these stores, and to these massive industries in our country, and say, “God sent us by here, to say to you that you’re not treating his children right. And we’ve come by here to ask you to make the first item on your agenda fair treatment, where God’s children are concerned. Now, if you are not prepared to do that, we do have an agenda that we must follow. And our agenda calls for withdrawing economic support from you.
Radical Discipleship 
Abused African American People chose not to listen to Dr. King, and they decided to keep paying and supporting White Businesses. That only used the African American Dollars to buy bigger Shoes to kick them in the Asses with. Maybe if African Americans would have stop giving White People their 30 Billion Dollars. Whites would have started respecting the $30 Billion Dollars they would have missed. African Americans disregarded Dr. King and continued to pay the Whites instead of Economically Withdraw from giving them our money. Whites enjoyed even more to keep getting African American Money and to be able to kick them in the Asses with new shoes that the African Americans bought them with those $30 Billion African American Dollars
