What's the visa climate like there? You don't sound very jazzed about the long-term prospects of living in Argentina.
Actually Argentina might be in for a recovery in the mid-to-long term. Some things are definitely changing. For example, in 2016, after the Peronist monopoly in power was broken, it was the first time ever that a Jew was appointed to the Supreme Court (and today he was announced to be the next president of the court); there is active prosecution of politicians, businessmen and drug lords who all conspired for (read this in Palpatine's voice) UNLIMITED POWER, and the covert rampant xeno-/Anglo-phobia is at a stop, at least for now. But always this kind of transition means that there will be a temporary low point (assuming the country pulls through).
Elsewhere… Europe's veering towards the far right, the US is a shambles, Canada is a possibility, Australia is also a political wreck, so… New Zealand?
Maybe Xhosa and Swahili aren't as far apart from each other as Gaelic and Turkish.
Just for the record, the Turks did raid northern Europe several times for slaves, going as far north as Iceland. Read up on the US wars against the Barbary pirates, it's as outlandish to a present-day reader as reading about warlike Tibet attacking China, the US fighting Austria-Hungary for oil or a Jewish nomadic state on the border between Europe and Asia.
I knew you spoke Spanish from this forum, and I'm glad to learn that you also are facile with written English. It's a good language to know.
You can probably get a job teaching either English or Spanish in China. No Chinese required.
Actually, English is
not so easy a language to master. Sure, compared to Finno-Ugric languages with a couple dozen grammatical cases or Slavic languages with three or four dozen letters in the alphabet, plus a highly complex verb conjugation system, etc. it might sound simple, but
a) English actually has such ideas as plural and singular, verb tense, aspect, mood, and so on, which hundreds, no, thousands of millions of people don't have in their native language (as you say, Chinese and half of South-East Asia) and find it incredibly hard;
b) the spelling is so inconsistent with the pronounciation that it's basically a system of mnemonics;
c) there are so many possible pronounciations for any given word, according to accent and register: rhotic and non-rhotic, mergers for w and wh, for a and e, for e and i, etc.;
d) there are so many metaphors and figures of speech, also so many near-synonyms with only tiny differences, nuances. Think that, for ESOL, one classic topic of examination is ‘ways of shining’ which people such as me learn at an instinctive level, or ‘ways of moving/walking’;
among others.
So very often teachers of English are underestimated.
