Powell says that Private waste-removal is more efficient. His reasoning is the statistics he cites.
Freeman does not disagree with his conclusion but says his conclusion is not justified. He does this by attacking an assumption of Powell's. The idea they are serving customers with same needs.
Freeman says that, since they choose their customers that helps them in costs. He could just as well finish and say this is why they are more efficient.
I would like to know if this is the proper reasoning for this question bc Freeman never explicitly says I disagree. He might be thinking it.
