In US from late 90s to mid 2000s the price of housing kept increasing, dollar vs. euro plunged and dollar vs. many commodities dropped as well. But some how there was very low inflation???
Salary increases are also inflation-adjusted, which leads to unions calling governments liars, governments calling the unions greedy and liars, etc...
Inflation is a serious thing, especially in these countries.
The economist's spotlight on Argentina is due to the British establishment's dislike of the currently elected Argentinian government and England/Argentina tensions of the past decades.
Indeed the current situation in Argentina is very extreme in terms of democracy: people being prosecuted for thinking differently, the government building an explicit criminal association. The conflict with the Falklands is finished and the Argentinisn government uses it as smokescreen.
In the US, the inflation is so close to 0 that the index can be manipulated without rising as much suspicion.
