I agree with the sentiment about Uber, but there is a substantial difference. Uber will close them down when it stops to make business sense. A research professor is expected to be out on the street once grant funding runs out. Most postdocs are expressly 2-year appointments. Grad students get paid dirt, and have a ~7 year limit (depending on school) with random students kicked out at random points (qualifying exams, etc.). Neither is stable, but of the two, almost any industry, even including Uber, is much, much more stable.
