USA, Canada / Living 16+ years in the US. Is moving back to Poland a good idea? [14]

Recently I've been thinking a lot about going back to Poland but I'm not too sure if it's a good idea. I was born in Poland and lived there for the first 7 years of my life, and then came to live in the United States with my family. Growing up I would always say that I'm going to go back but everyone always told me that when I get older I'm going to change my mind and that I won't have half as good of a life there as I do here in the US but 16 years later when it comes to the urge to go back it never went away instead it gets stronger every time I go there for a visit. However I don't want to make any decisions without knowing exactly what I'm going to get myself into.I speak both English and Polish fluently & I'm in process of getting a teaching degree here in the United States but I don't know if the degree is going to mean anything in Poland. Is it possible to find a good job if I do decide to go back?
