I think the definition of “strategic default” is the reason why it is more common in “upper socioeconomic strata.”
To be a strategic default, you have to be able to afford paying the mortgage on an under-water property. Most in the lower strata are unable to do so, and thus their defaults are not considered “strategic.”
