I like this part, right here:

There is something emerging within humanity that has not occurred before.

I believe what is emerging is the realization that contentment is a skill. The angels you have noticed must be teachers, for each angel pictured in your post is holding someone else, not by the hand, but by the arm, and pointing to something else for greater awareness of the person they lead.

Those angels must be teaching contentment for what else is there to teach? Once we achieve contentment, the rest is easy.
