I think you need to visit Argentina and stay a few months, before committing to move from Korea. Its a different world, and there are many things you take for granted in Korea that are completely different in Argentina.
YES, inflation will, most likely, be a constant here.
The economy works very differently.
I keep saying- dont move to Argentina, unless you LIKE Argentina, enough to put up with its very odd and different way of life, economy, and eccentric ways.
Most Koreans are happier in the USA or Canada, where hard work can usually produce more predictable results.
