how would southern colonies plantation owners respond to wealthy englishmen nobles claiming that "property does not make an aristocrat"? why?

White southerners would pass laws that controlled the movement of African-Americans because African-Americans were a large part of their workforce. This was especially true during ther era of Reconstruction. If a large amount of African-Americans moved away from the South, it would decrease the amount of workers available to work on farms on plantations. If there were less workers, that means farmers/plantation owners would make less products, reducing the amount of profit they could make.

Each state wanted to be equal in their say but there was concern over how to determine representation.

Largely populated states preferred a system where population determined representation. This would give large states a lot of power leaving small states and slave states with less representation. The other concern was how to count slaves--as persons or property. If they count as persons, then the South would have many more representatives than Northern states. If slaves count as people, however, it creates a moral issue. The other option was a straight set number for each state. Again if many states fell to one issue then other states could be shut down. The compromise was to create a two chamber Congress with the Senate having a set 2 representatives from each state and the House being set on population. Slaves were counted as 3/5 a person as stated in the Three-fifths Compromise.
