Television talent shows are a poor way to kick start a music career for any individual. The traditional way that artists begin their music career is by beginning at the bottom before they are even known and eventually working their way up to the top based on popular demand and people engaging in their music and/or talent, not being forced to listen to a musician, etc and grade them based on their liking. It isn't the natural way that music careers begin.
Television talent shows are a good way to try to raise money quickly for your family, because its through your own musical abilities and dedication to providing for what you think is important. It's this mindset of "so what if its not traditional".
