my mom used to rent rooms out in the bay area years ago...typically for 6 to 12 months. a common scenario was a young german man or woman, having come to work for google as an engineer. in fact it was common enough that she developed a relationship with some person at google HR who would refer her as a housing option.

makes me think now how she was seeing the concept of brain drain happen before her...not just of say national brain drain from Germany to US, but moreso the brain drain from any engineer and their skills going into a US tech company instead of some other innovation or valuable economic activity.
