Actually I find that table a bit suspicious. The sequence of countries ordered by pay gap (lowest to highest) is the following:
Romania, Costa Rica, Luxembourg, Belgium, Bulgaria, Greece, Slovenia, Italy, Denmark, Turkey, Norway, New Zealand, Colombia, Malta, Hungary, Poland, France, Iceland, Ireland, Mexico, Spain, Lithuania, Cyprus, Netherlands, Portugal, Australia, Switzerland, Slovak Republic, Germany, Czech Republic, Austria, Finland, United Kingdom, Canada, United States, Chile, Latvia, Israel, Japan, Estonia, Korea.
See the pattern there? Neither do I. Usually there is some correlation by continent, cultural area, GDP, HDI, etc. In this case there seems to be nothing. Romania and Costa Rica and Luxembourg are the countries with the smallest wage gap; Netherlands, UK and US are way up there, in company of Chile, Canada and Estonia. Turkey is wedged right in between Denmark and Norway. Netherlands' pay gap is 4 times that of neighbouring Belgium. Mexico and Ireland are the same. Lithuania's gap is half that of Estonia and Latvia. Strange.
