For various reasons and from different aspects, real globalization happens when we broaden our view, see new horizons and evaluate the real trade-offs from different perspectives and various parameters.
One important, often overlooked aspect is the presence of our citizens in many parts of the globe adds up to the global exchange of or intersectionality of culture, knowledge, languages, different practices and systems prevailing in different regions.
Otherwise, availability and usage of most modern technologyical and facilities are accessible to many in most developed nations more or less at the same level ( though there may be some shortcomings in infrastructure and ' real ease of doing business'.).
The practical experience that one derives out of physical presence and operating in a different environment ( whether better or worse than ours) is something that has immense value.
