"Artists are often asked to donate their time and talent for exposure rather than for pay.  Most often, it's a something-for-nothing exchange and the musician is the one that comes out with nothing in the end.  Musicians develop their craft, write their songs, rehearse and arrange and practice their stage work for the sole purpose of being paid.  Exposure is not payment.  Similarly, often times experienced managers are asked for counsel, advice and strategy without any kind of compensation.  Would you ask your Uber driver to work for free?  How about your doctor or any other professional?  When a manager is generous enough to give you sage advice without any payment strings, be appreciative of the generosity; but also understand that managers work to earn a living, too, so free help might be temporary.  Just because some of the best managers love their jobs doesn't mean any artist should assume that a manager will work for "the exposure."
