Greetings, interesting post, and I think there is still a continuation or I'm wrong?
I think that a lot of this can be seen in our society, both in governmental bodies, as well as in our own community, neighbors, etc.
I was struck by the classification in the types of personalities or characters, making me see and try to locate myself in one of these groups described above. Can you belong to several groups? Can you have qualities of one group and another?
I can also appreciate that they have positive and negative aspects, although in some cases the negatives outweigh the weight, I have had the opportunity to meet people located among the "opportunists" and I believe that although their only positive aspect is knowing and observing their environment, I consider that This is part of his personality, since when he observes he realizes who can take advantage of him and from whom he can get some kind of profit and benefit of his own.
