She is a princess. I like to think of Themyscira as a rich and wealthy country that just doesn't NEED all that treasure and power because they don't really trade with others. But I also like to think that when she came to man's world her mother gave her "things barter" i.e. coins, jewels, artifacts to hock. She's rich. I would love for the Diana Prince id to come back at some point and there be some sort of talk about her being an investor in Wayne Corp...
She can also open her own business like teaching them the amazon way even though they don't know it.
Alternatively, she could set up a martial arts school.
If hard work is not another name for talent, it is the best possible substitute for it.

Any city/business/rich person would glady sponsor her to stay there :)
