What's development

"A developed country is not a place where the poors have cars, it's where the rich uses public transportation"

Few weeks ago we talked about the difference between economic growth and development. Economic growth doesn't necessarily mean people's quality of life will improve. For example China is becoming a big economic power, but democracy there is still weak and chinese don't have the right to say openly what they think. They're getting rich in  material things, but they're poor in democracy.
On the contrary there can be poorer countries caring much more of the environment, of citizens' healthcare and education, and last but not least of their opinion.  Where would you prefer to live?
The Mayor of Bogotà, a big city in South America, explains the concept with an effective example: development is rather shown by an efficient public transportation that reduces car traffic and makes our cities more livable, than by a big amount of expensive cars in the roads.
Of course a country can be rich and developed at the same time. That's still the best.
