why would some artist charge as much as they can for a ticket to their concert while other musicians make a serious effort to keep their ticket prices affordable

Most of the time the some artists preform in bigger places which costs more money and soo the tickets are more expensive because it makes up the price they paid for the place even tho they are already rich but like some artists know how it feels to not be the richest person soo they keep it affordable soo everyone can come but it means more people less money in a way I believe
