However, there are objective indicators for accomplishment and success.
One of them is if whether a Western FT re-integrates without problems into his native
enviroment when returning from a place like China - whether he has a job, a home, an
income and does not need to struggle for survival but has a convenient life instead.

Professor, that textbook definition would exclude a large percentage of famous authors and painters. I would suggest that Paul Gauguin, El Greco, Jonathan Swift, Oscar Wilde, Emily Dickinson led productive successful lives even though they never integrated well with society and/or failed to accumulate the trappings of comfort and wealth.

Struggle defines us, not stuff.
