I don't think metros are the worst choice we can make, but let's get a bit real.
Imagine a third world metropolis,which has multiple
deficiencies: health,education, urban transport,culture, etc. Does it seem fair
to invest a hughe amount of money in a subway system instead of investing in
some other aspects that are equaly important? Does it sound sobad to invest in
alternative modes like express buses or double buses?
