Thanks Rex, Yes what isn't here is mostly due to lack of time. It takes time to study each article. Determine how relevant it is, find the best quotes etc.

I want to find the articles that are very hard to deny the results of. People will find any possible excuse to reject studies on this topic, so I want ot include primarily stuff that is solid.

Yes I would very much like to include the job prospects studies. If you got some and with maybe a line explaining why the study is important, I would love to include those in the list as well.
