In the globalized world “purchase power parity” is a necessary and an important consideration. However, this is never discussed in most of the printed news.
Reasons for this consideration are very simple. Except for few financially savvy individuals, majority does not understand it.

This is especially true when British pound, dollar, Euro, or other currencies are converted to currencies of supposedly low cost countries.
Normally Press converts the foreign currency to the currency of their readership. Since the readers are not familiar with the purchase power of one currency to the other, reader gets the impression that the people are living in poverty or living like kings. The disparity between the absolute numbers is the reason why the jobs are going to low wage countries.
