Would you go into teaching? For me, I don't know...

The goal is not to hire good teachers, certainly not the best teachers, the goal is to hire the cheapest teachers.

At the college level, teachers have to jump through lots of hoops, gamble and spend a lot of time and money to get their PhD in the hopes of getting on a teacher tenure track that can last 6 years. I think the odds are around 50% don't make tenure. 

Otherwise, they go the adjunct route in which teachers often have to live on less than what someone gets paid as minimum wage. Colleges won't let teachers teach more than a couple of courses as an adjunct. 

The question I wonder is if the system can be hacked? Take on a bunch of online adjunct jobs at multiple colleges so that you are teaching around 200 students total to bring your wages up to 6 figures. What about the workload? Well, hire a teacher's assistant in a 3rd world country to work remotely.

SNHU, for example, pays their adjuncts $2200 for a class size of 20. They charge $960 per course, costing them as little as $110 per professor. Pretty good deal for the college.

I´m teaching in Peru at 1 state university (1 course), 2 private universities (2 courses and 1 workshop), 1 institute (5 courses) and 1 center that teaches PG Diplomas and certificates (1 course):

State university: USD$ 4 per hour 
Private universities: USD$ 9 per hour 
Institute: USD$ 5 per hour
PG Diplomas center: USD$ 10 per hour
