This a movie entitled Space Traders. It is based on a short story written by Derrick Bell.
In sum, America is at its wits end. The economy is busted. Suddenly Space Traders appear and offer the American Government the money to make the country rich again if they will give up all of the African-Americans. Well, you can predict the end... Whites who have longed believed that African-Americans are a drain on "their" country give up the goods. Blacks are marched off American soil like slaves at gunpoint into space ships.
See for yourself!!!
