It's not very much related to writing lol. I was thinking more about paid reviewer or something, but have no idea if there's market for it. Other than that, a professional movie reviewer sounds like fun too!

Right, but there's too much competition (not only humans from low wage countries but also machines). Working online is getting tougher. I thought of becoming a teacher one day, maybe :).

The problem is, most website operators (companies) care about their bottom line and they have no problem working with an inferior writer from a developing country if they can pay him/her substantially less than a well-educated native English speaker. A student (client) doesn't see a big difference in quality, either (because he/she is not qualified enough to judge the writing/research quality).
