"exceedingly talented individuals arise and can have a profound effect"
Key word there is CAN. Yes, exceedingly talented individuals CAN arise and CAN have a profound effect. It doesn't mean they WILL. It doesn't mean it will happen in an individual's lifetime. A talented individual might not arise and have a profound effect in his or her lifetime. Vincent Van Gogh and Emily Dickinson were among the many talented individuals who were barely recognized in their lifetimes.
It makes me wonder just how many talented people go unrecognized FOREVER. How many talented individuals never truly arise? For those who never arise, is it due to a lack of talent, or is it due to other factors (including a lack of luck - yes, luck DOES play a role)? Since we'll never know about those unrisen talents, we'll never know the answers.
I once knew an artist who could have done work for a major comic book company (he's THAT good). Although at one point he did win some character contest at some comic book company, as far as I know, that was his sole claim to fame. For all intents and purposes, this exceedingly talented individual (and he is TRULY exceedingly talented) remains a relative unknown, what you might call an "unrisen talent".
As for the money side of things (after all, in a capitalistic society, effect/success = monetary gain)...Edgar Allan Poe was among the many talented people who never made enough money to support themselves. As something of a "starving artist" myself (a published poet/writer/artist/illustrator who is not making enough from sales of his creative works to make a living off of them), I can relate to Poe's woe.
I'm not sure the article here gets all the details exactly right, but the general spirit of the idea is what I'm really after anyway:
