I can sympathize with people who have families when they talk about how expensive SF is, but when single people do it, it's almost always possible to cut their spending in half and still live comfortably, they just don't want to give up the little luxuries they've accustomed themselves to.

Wholesale pricing is a good strategy, correct. This isn't viable for everybody, or even for most people. Not everybody can live this way for various reasons, and certainly many engineers that I've interacted with aren't able to or need the alone time to be productive.
I've seen a pretty wide spread of living situations. I wouldn't call anything I said hyperbolic.
