Good paying jobs In Germany?

I will be graduating high school next year and I want to figure out what I want to major in. Pretty much I just want a job I will be able to have a good income off of. Right now I live in the U.S. But I want to move to Germany after college. What career will allow me to be able to make enough money to live in a city like Berlin. I've done my share of the research too. I already know that living in the Europe area is a lot more expensive then the US. I thought of Becoming an ESL teacher because thats supposed to be in high demand and pretty good pay but i'm just not sure. Thanks for any help you can give me.
