Attention teachers! Which masters degree makes the most money?

I will have my BA degree and certification as a teach for grades 1–6 with general ed. I double majored in English. It will be time soon to get my masters and I want to get it in something that makes more money. What are good master programs? Which direction should I take? So far I hear early intervention, ABA, and special ed. Any help with this would be greatly appreciated.
