A lot of the issues raised in this article (low or zero stipend, poor job prospects after graduation) are more appropriate if you're talking only about the social or life sciences.
In science and engineering (engineering in particular), PhD students rarely have to pay their own way, with stipends around $25000 or even up to around $30000 with a fellowship. The job prospects are certainly a lot better as well- since research funding in the US is very much focused on science and engineering.
