Yes, this is another inspired poll, and you can make 1,000's similiar polls if so desired.
But consider this: we already tell our high school students in many states they must perform community service, and prisoners are sometimes found doing work, at least they were in the past.
Making prisoners perform labor is not slavery; it is part of punishment for a crime. Slaves committed no crime other than being born with the wrong skin color. So the two are not comparable.
Neither is the high school community service requirement. That is a minimal and short-term commitment, and intended to be enriching to the student as well as the community. You might just as well call homework slavery.
As an aside, at my high school, they sometimes used to make students who got in trouble for breaking rules do work details after school as punishment. I wish I had known my "rights" back then; I would have contacted the ACLU about it.
Of course, I voted no slavery under any circumstances. What other way is there to vote?
