I am trying to figure this out myself. I am originally from here so I had pretty low expectations to begin with. I was making a nice living working in upscale restaurants in the US. Even when I worked at mediocre ones at some point, I could feed and clothe myself, go out on the weekends and take the occasional vacation. What little offers I see in the market here are somewhat discouraging though. Most fall around the USD 300 monthly take home pay, barely over what I pay for the room I'm renting.
I was curious about the English teaching option too. I gave a few lessons to an ISIL student and got PEN 20 per hour, having to travel from Pueblo Libre to La Molina. I am currently working on a TEFL online certification that I hope can broaden my appeal and increase my compensation
but we'll see.
I agree with you: there has to be something better than working minimum wage for 48 hours a week. I just don't know where it is and no one is telling me. I keep sending resumes out but I have a feeling they are going straight down a black hole. I realize I will never make close to the same money I was making in Seattle, but is there a middle ground of decent wages for experience and hard work? Because I bring both to the table.
I don't despair, however. Growing up my folks would work several jobs/ventures at a time; diversification is the name of the game. While stressful, I would rather work part time in a restaurant (if that even exists) and teach English on the side, precisely because I would prefer to avoid being locked inside a place all week for 300 bucks. If I don't make any more than with just the one job, maybe I can at least retain a somewhat flexible schedule so I can still go to the gym or take a class.
Good luck to all of us!
