In someone's thread that was posted here, an ENTP was described somewhat like that. That is, the "kid" that "leeches" of his big-time parents' wealth.
Being an INTP myself with strong E and Fi, I often associate myself, and to a certain extent, empathize with ENTPs, ENFPs, and INFPs. They're the other archetypes that I can easily relate to other than my own.
I thought that it was a smart statement. I know a significant number of ENxPs myself and this is something that I observed to be true, but for the fear of having a hasty inductive reasoning, I tend to overlook, sometimes ignore, that observation.
Basic profile would be something like this.
Has a good bearing. You know that the person is considerably educated. The person is considerably articulate and you'll know immediately that he came from a good family background in terms of affluence.
But closer inspection will show you the difference. The person dresses more casually. He isn't the one who would readily acknowledge his parents' wealth (maybe because the accusation of leeching is bad enough).
He knows the mindset of a person who has a strong Te, but in reality, he's really anti-corporate himself (sometimes even advocates socialism) and would even advocate the path to least resistance (Ti).
I have a hunch that if the ENxP person grew up in a Te heavy family, he might see something wrong with the cognitive process (e.g., Te's advocacy of THE ENDS JUSTIFIES THE MEANS), therefore, consequently making himself advocate the polar opposite = Process over results (Ti), or maybe to some people, Fi (the known weak cognitive process of someone having a strong Te).
Did any ENxP here feel that at some point (assuming that your parents could be rich Te monsters), you need to develop whatever weakness they have so that there'd be a sense of equilibrium in the family?
Anyway, I know that NP is quite childish. At first, it was hard for me to embrace this (even if it may be inherent) because I was taught responsibility in life (SJ) way too early. I think this may have caused a sort of drawback in me later in life by rekindling a childish playroom I wish I have more of. I think that's part of what makes me NTP now.
