It takes a certain kind of mindset to become a teacher. You need to have not only accumulated a lot of knowledge, but also to have a passion for sharing it with others. You need an excellent memory, great communication skills, the ability to inspire others and the mentality to cope with monumental amounts of stress. Home Economics teachers may have it harder than any other specialism within the field, because of everything they're required to know.
Home Economics is really several subjects rolled into one. The subject teaches children how to deal with real life; how to understand and file taxes, how to cook, how to make a financial budget, how insurance works and so on. That means as a teacher you have to know the intricate details of all those topics. It will take you ten years of experience as a teacher to accumulate that knowledge, as well as a Ph.D. and the relevant licenses. It's a long, hard road to $100K, but the route is open.
