My sister has lived and/or worked in SE Asia; Viet Nam, Thailand, Malaysia, and Myanmar. Nepal, Hawai'i, Florida, India, and France. Travelled to CH (Switzerland), UK, Eire (Ireland) and Vermont.
Yet , she now cannot get suitable work in the 'states. Even w/BA degree. Her age and arthritis now precludes a lot of jobs; they only want young, irresponsible kids still living at home. She cannot afford to move to Greater Bay Area where she Might get work. No retirement built up, she had to dip into family trust to pay plane fare.
Hardly anything to be "jealous" of.
