Living in the world's most expensive city

Aftica's Most expensive city? Or the worlds most expensive ?
So why is a city like Luanda so expensive?
There are several reasons. The main one is that Angola lived through a long civil war which started in 1975, when the country gained independence from Portugal, and continued right up until 2002.
Infrastructure is in poor shape after more than 20 years of civil war
During that time most industry, agriculture and local production stopped and basic infrastructure including roads, railways, electricity lines and water supplies were badly damaged.
Having once been a major exporter of products like coffee and cotton, and self-sufficient in most foods, Angola now imports an estimated 80% of its consumable goods.
For every tin or packet of food you buy in Luanda, you must factor in the cost involved in getting that product to Angola and onto the supermarket shelf, via a congested port with its highly bureaucratic customs and a traffic-clogged city.
There are some cynics who say Angola's business elite, who control the import companies, have also done little to bring down costs, although in recent years bringing down prices has been cited as a government priority.
