You've also got tons of both locals and expats trying to do traditional self-fulfilled e-commerce...hang out in a post office like the Nana one for much time and you'll see 'em.

It's easy to envision someone retired on Social Security only and wanting to pick up extra income as long as it's not a real pain to do. You can also be based at or somewhat near a hub like BKK and do the ULCC round-trips as your travel rather than going point-to-point.

A decade or so ago a retired friend who also played the mandolin ran across some beautuful mother-of-pearl encrusted ones in Vietnam and was considering selling that. He even could test them first. Unfortunately if sent by air there was some problem with pressure differences and they'd crack.
