I completely disagree. I went to Hack Reactor in 2013 and the ROI was fantastic.

I really leveled up my JavaScript and coding skills in general and ended up dramatically increasing my earning power. I was hired about a week after graduating and just the signing bonus paid most my tuition.

If I ever see a similar kind of school for the next skill I want to build, I'll probably enroll.

That said, I've heard some of the Lambda School claims and don't believe they're honest. Vincent Woo did some solid reporting on Lambda.
