Since you're lazy; I'll bring it to you. For around the third time; there was a compromise because the southern states wanted slaves to count as a whole person.
Since I'm done with your ill-informed arguments: "But by giving the South power disproportionate to its free population, the three-fifths clause set the stage for Southern control of the federal government and, in conjunction with a difficult amendment process, guaranteed a continuation of slavery."http://www.nytimes.com/roomfordebate...ise-on-slavery
Here's the wording of the amendment: "Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons.".
Clearly the only people who benefited was the slaveholders. You done being deliberately obtuse?
