I think all countries should name their capital cities after the country...... such as Mexico, Djibouti and Panama have done....... make life easier for us Jetpunkers.
I was also surprised. The economy of Singapore is larger than the entire country of Pakistan (without this PPP malarky). It's bigger than all of Bangladesh and the Philippines, too. Pakistan's got a bit more than 5 million inhabitants.
I still think that PPP makes sense for comparing people within countries, but not for comparing the countries themselves to each other. What does a country care how much a burger costs in the other country? How does that relate to relative economic power?
