It is actually very common to go to a research facility after a PhD. Anyone with a doctorate from a reputable program will have a list of publications that demonstrate a clearly defined interest and quite possibly even grants. For those that aren't at the level of a research scientist, there are often post-doctoral fellowships. If the companies are large enough, grants are less of an issue because there is a built-in R&D budget. There is less of the panhandling you see in academia.
