Three kinds of Indians

One of my relatives tells me that there are only three kinds of Indians:

- those whose homes are dirty inside, and outside which there is filth (the poorest, mainly in urban slums)

- those whose homes are clean inside, even though there is dirt outside (the vast majority)

and

- those whose homes are not only clean inside, but they live in a context where there is cleanliness outside too.

He opines that the last and most privileged category may number only a few hundred thousand, at most.
