There must be clearly a second class of H1-B holders I've not encountered before, those that are actually planing to go back to their country of origin. Most H1-B people I've worked with used the H1 process to clear any immigration hurdles due to their previous F and J visa, which often required return to the homeland for a certain amount of time. The H1-B than gave them a period to get permanent residence.
I've seen the "live on the cheap" version before, typically with Indian and Chinese graduate students, so it might very well exist in the DBA H1-B world too. And maybe DBAs are more interchangeable than scientists, and having true short term employees is not a detriment for Microsoft. But in most fields you want to keep your technical staff around, not having to replace it every 3 - 6 years due to visa rules.
