Using examples taken from the text give me a summary of the main arguments in favour of slavery reparations in the United States and the anticipated cost of enacting such reparations
In spite of progressive changes since the end of enforcement of Jim Crow and the successes of the fight for civil rights there are still inherent racial inequalities in the USA which negatively affect the civil, political, economic, social and cultural rights of African Americans today.  A United Nations report of 2016 did not endorse a specific reparations proposal, but did call out that there is an ideology of white supremacy present in the population of the United States that inhibits social cohesion.  Further arguments have been made identifying slavery as a cause of mass incarcerations, poverty and other ills that affect today’s African Americans.
It could be argued that there is an inherent acknowledgement that the case exists to examine the impact of slavery on the social, political and economic life of the United States in the annual submission to Congress of the "Commission to Study and Develop Reparation Proposals for African-Americans Act”.  There are also individual cities within the USA which have instituted reparations.  Estimates of the cost to African Americans of the United States’ history of discrimination have been estimated variously at $1.4 trillion, $4.7 trillion, $5.7 trillion, $14.2 trillion and $17.1 trillion.  These estimates express the projected cost in $ to restore the black community to the economic position it would have if it had not been subjected to slavery and discrimination.
