Is this a reference to Amazon being disproportionately Indian?
Class is also a generalization: I'm a gainfully employed SWE, and I (by choice) live in a neighborhood where I hear gunshots nightly. I don't own any new clothing, my nicest pair of shoes are my work boots, and my friends are almost entirely blue-collar people. I could easily afford to live like an upper-middle-class yuppie, but I border on lower class at first glance.
Is class entirely economic, or is there a social aspect?
