If there are truly wise people in this world, in which line of work would they most likely be?

The problem with such a question is that there is no agreed definition of the word wise.

So a religious person might choose Religion and a worldly person might choose Government while a person who personally feels no great need to own things might choose Philanthropy. However I suspect that the wisdom that the religious person has in mind is not the same thing as the wisdom that the Government person has in mind and while the religious might think they have a lot in common with the philanthropist the philanthropist might disagree.

Etc.

I feel that the smartest people stay out of the lime light. They embrace family & friends, live to serve others and find daily gratitude in simplicity. They maintain a sense of wander and awe.

It could be any or all of those. Wisdom doesn't really have much to do with line of work or age. Unless one just "thinks" he's wise and chooses based on that.
It's a gift to some and they most likely won't be trying to prove it.

Hopefully teaching...

Definitely Teachers. Like your high school teachers. I learn more from them than I did my professors

I'm a brine taster over at the pickle factory but I'd rather be an olive stuffer.

We need wise people in every walk of life.

Science or medicine would be my guess.

None of those lol 😂

Be a humanitarian.

There are probably wise and unwise people in all those professions

'Influencing'.

The answer is in the job title....

You should have an ‘all ‘ option or something
