Saturned alluded to, tend to put faith in others' "MBTI status". Those that don't also don't really give a damn about the opinions of the people they are typing unless those opinions give weight to their own reasoning.
If I had to guess, I would say the most well liked type in the states is ENFJ, while the most admired type is ENTJ. Psychologically, INTJs aren't a far cry from ENTJs, but they lack the qualities that make the ENTJs on par with ENFJs in terms of how "good" they are. They tend to come across as melancholic because they either retreat from the world or silently navigate it if it is agreeable to them. Developing or accepting a code of honor is (I would guess) key to them finding their circumstances negotiable and ultimately satisfactory on some level.
As far as "the grass is greener" thing, the only things I've been praised as by NTs is being "psychic", "funny", or "charismatic". On the other hand, they also give me a lot of shit because I try to be "okay" with everything while also participating in everything. It can be a recipe for disaster unless feelings of envy, on my part, are dealt with properly.
