What it is like here
Argentina is the case where the machinery runs out. The World Bank stopped publishing the price data that every other living-cost figure here is built on, because the exchange rate stopped meaning one thing — so this page carries no living cost, and the school fees could not be established either. What is here is safety, schooling quality and the residence rules, and those are worth reading; the rest is missing and says so.
