Please realise that at the moment the situation in Spain is the same as that in the rest of Europe and America - there are very few jobs available. University graduates who might have gone into industry in the past are now entering teaching so there is a surfit of teachers.
There are very few jobs in Spain - the tourist trade is not the best at the moment as the British are not taking the number of breaks abroad they have in the past.
If you can find work in America then please do so - if not extend your education and get the appropriate qualifications to be a teacher. Don’t think - its OK to teach English because I can speak English - it’s not. You speak American English and that is not good enough for the Spanish children you will be teaching - they deserve the best - Qualified English Language Teachers.
Tourists most welcome - otherwise - stay in your own country until after the recession.
