what are you laughing at exactly?

I personally found the quote to be in poor taste to a certain extent. He's talking about experimenting with people's lives. Yes, the students agreed, at least in some sense, to be a part of the experiment, but it is still a rather callous response in my mind.

I basically came here to say this, as that comment stuck out from the article for me. I was thinking, that it must be nice to experiment using students' tuition money. I'm pretty sure the student didn't expect to be part of an experiment when they signed up.

He's trying to see a positive aspect. He isn't quoted with everything he said.
