Pros
Make a Name for yourself. If yours is Good then Half the World will know your Work, your Name. and your Impress upon It All: your "Take," your given "Apprehension," may indeed be found to Bear upon the Poise of the World and Its own Zeitgeist be the very Drift upon Which We Amongst Men on Earth should be given to Catch It
Cons
You'll never see a dime; this' Pay-To-Play, All The Way In, uh huh . . . but you'll never work again. No, not Anywhere, doing anything - though you will be afforded no way by which to possibly anticipate this. And all the way Along the Way. You will Only ever be Very Carefully Lied To, until finally you are Railroaded all the way to the Bottom, and utterly squandered for anything at all you were ever otherwise Good For. And, No: You shall Never be given the Why.
