How can people who run ITT tech live with themselves?

I'm a little sad that I am hearing about ITT tech. The fact that they are using people that think that they are making their dreams come true and really they are just being used in a scam. Some people's lives are ruined because of ITT tech. I see their commercial come on all the time and they talk about how you can get a degree in a short amount of time then you can if you were going to college like what I'm doing right now. I always felt that there was something that was off about that because if that was true then you would have high school kids flooding that place with applications. How are these evil people able to operate when they know good and well these people won't be hired to the field they are in. They will never be cops, programmers or any of that; they will be in more debt because of that place. This pissed me off and I'm thinking about doing a film on them exposing them even if I may be sued for everything I have, this really bothered me and I'm only 20 and I don't have much but what little they may take from me for "slandering" I am willing to lose.
