Looks like our country an average student when it comes to retirement planning.

The U.S. pension system earned a “C” grade on the Melbourne Mercer Global Pension Index. It joins Mexico, Brazil, France Germany and Poland in the “average” category. Denmark was the only country on the list that received an “A” grade for having a first class and robust retirement income system that delivers good benefits, is sustainable and has a high level of integrity.

It’s hard to compare pension systems in different countries since all are organized differently and every country has to contend with its own economic, social, cultural, political and historical circumstances, but the Melbourne Mercer Global Pension Index measures each country’s system against more than 50 questions it believes should apply to retirement systems everywhere.
