And are there any first-world countries (except maybe the US^^) where a 13" Macbook is several times the average net monthly income? In Germany, for instance, the monthly average net wage (MANW) is €2500, while the price of a 13" Macbook starts at €1300. Italy: MANW is €1700, Spain: €1800, France: €2400, UK: €2200. Go to the Nordic countries, Switzerland, Ireland, Austria etc. and we're talking MANW of €3000+. Canada has MANW of around US$3400.
^^ If the US is the only first-world country matching your statement, one could argue this is further evidence that the US is no longer a first-world country.
