Answer:
Think about slavery. The average African-American will have very low morale if he is forced to work. Low morale means their work ethic will slip, and sub-par work ethic leads to sub-par product. You'll actually be saving money if you free your slaves. Rather than paying tens of thousands of dollars to buy them and then paying for all of their expenses beyond that, you'll just have to pay them monthly or weekly wages. Abolition is both cost effective and stimulating to the economy.
Explanation:
Large concentrations of individuals were more expensive to care for, especially medically. Most slave owners were primarily concerned about the so-called "wage bubble" that would burst and leave all slave owners destitute, when in reality slave owners who freed their slaves and still had some working for them as freemen flourished.
Slave traders violently captured Africans and loaded them onto slave ships, where for months these individuals endured the “Middle Passage”—the crossing of the Atlantic from Africa to the North American colonies or West Indies. Many Africans did not survive the journey.
Not sure it did limit freedoms of Loyalists post Revolutionary War, however during the war I imagine ones that lived in Revolutionary controlled regions were restricted in movment and expression. Most Native Americans however, sided with the British because of the proclamation of 1763. This was an outcome of the French and Indian War and prevented colonists from expanding west of the Appalachians to prevent more conflict with natives. Colonists did not like this, they wanted to expand as far west as they wanted.
