Brother, I do not think that I ever wrote that ‘why Pakistanis can’t pay international prices’. I may have written that Atta prices in Pakistan has gone up because international prices has gone up and for Pakistan to develop, Pakistani and international prices have to converge (obviously, along with wages).
Anyhow, thank you for the reference on minimum wages. Actually, I was looking for such reference since long time 
As far as my statement regarding minimum wages is concerned, I have to correct it a bit after taking your reference into account. Instead of writing what I wrote that, Pakistan minimum wages increased from less than $25 (1999) to $80 (2007), I should have written that minimum wages increased from around $27 (1999) to $80 (2007).
Your reference did cleared a lot for me and I learned that minimum wages was fixed Rs 1500 in 1993 (BB government) and after that it did not increased until 2001 (Musharraf government) when it was increased to Rs 2500. Big difference is that minimum wages after 2001 increased every year (that I know) and today it is Rs 6000.
As for mahgayee allowance, what I know, that payment is only applicable to people working in government but employees in even regulated private sectors could not get it. Hence, minimum wage in country stayed what law says, that was Rs 1500 from 1993 to 2001, when it increased to Rs 2500.
As for wikipedia, anyone can write there including you and me, so information is worthless unless it is backed by proper reference, and writer of minimum wages in Pakistan on wikipedia did not give any reference to back the claim. Anyhow, if mehgayee allowance is taken into account, still it seems that lowest wages for government employee was Rs 1950 (around $35) in 1999 compared to $80 in 2007.
