There's a well-known problem in Brazil with English acquisition. This is due to the actual need for it (or rather lack of), the false "become fluent" promises by the language schools (like CNA, Fisk, Skill, Wizard, etc.), the cost of taking a course for the student, the methodology of said schools, and the lack of daily contact with people from other cultures in Brazil (tied to my first point).<p>As for the teacher, working in a school like the ones mentioned, you get low pay (not too many years ago it was about $7/hr) and no leeway in terms of hours and method. Being a private, one-on-one teacher, though, one can command higher prices ($30-50/hr in the largest cities) and have more control over everything (just not always whether the students keep their appointments).<p>Nonetheless, cool video in the link.
