Learn English – What do you call a person who conducts seminar workshops

It will be in any case a criminal, maybe a career criminal. When it goes to drug business, you call it a druglord, which in himself is a kind of kingpin. You can choose your poison.

But in the end, without contest, the word which would best fit your definition is a racketeer, although career criminal or illegal businessman are not bad themselves.

For someone with money, "wealthy" is the obvious answer (and connotes various kinds of abundance).

For someone with social resources, "influential" or "well-connected." If you want to suggest that they don't often use these resources, but that people would do things for them if they asked, you might need a more specific term describing the nature of their standing, such as "respected," "popular," or "well-loved." If it's just because they're powerful, then maybe "powerful" or "important."

For someone with intellectual resources, a person who knows a lot of things might be "knowledgeable" or "widely-read," or they might be "a polymath," a "jack-of-all-trades," or a "renaissance man/woman." Or they could be "clever." "Clever" is sometimes used as a subtle insult (or as conspicuously faint praise) to refer to someone who has intelligence or problem-solving skills but uses them for trivial things.
