I think you misunderstood my comment. I was countering the claim that positive rights (such as the right to healthcare) cause slavery (for the doctor). In the context of TeeMassive's comment, he was implying that doctors would be forced to provide their labor to patients if the government declared a right to healthcare. My comment about how the right to childhood education does not cause slavery was referring to the teachers point of view, ie. that the teachers are not enslaved.
