No visa required. Who has most freedom to travel?

Recently I found very interesting information in Economist Magazine regarding freedom to travel without visa and sample list of countries with privileges like that.  Here is a link  and article below.

THE ability to visit a foreign country without the cost and hassle of obtaining a visa is a welcome bonus for any traveller. It is also a barometer of a country's international alliances and relations. A report released on August 25th by Henley & Partners, a consultancy, shows that Britons have the fewest visa restrictions of the 190-odd countries (and territories) for which data are available. British citizens can enjoy a three-day stay for business or pleasure to 166 destinations without needing a visa. Generally, citizens of rich countries and trade-based economies have more freedom to travel than those of countries suffering from war or repression. Compare, for instance, the restrictions on South Korea with North Korea and Hong Kong with those on China.
