I am glad Richard Arnold raised this issue. I never fail to be amazed at our unwillingness to learn from the history and progress of other countries. This is often reflected in our failures in foreign policy.
At least 20 countries are on the path of Social Security partial privatization from Poland to Australia, from China (of all countries) to Brazil including the most culturally close country Great Britain.
Those who are against some form of privatization always focus on the negative aspects of these reforms. They fail to mention that many of the problems have been solved by now. And even if some of the countries have not arrived at the best solutions, why not pick the best systems, avoid the pitfalls, and adapt them to our own peculiarities.
The Cato Institute and the Heritage Foundation in particular have published a number of reports discussing these foreign systems. See my web site:http://members.aol.com/adseale/socsec.html
