This is about the dred Scott case the question is what consequences did this decision have for free blacks.​

Even if you were in free territory, you could still not be free because of the slave code.

while it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton.
