In 1970, BD (then east Pakistan) vs. west Pakistan was 33.7% vs 64.3% of the total Pakistani GDP. In 2014, it has risen to 40% vs 60% of the combined GDP. I think, our rising economy is great considering how much of BD's export earned capitals were systematically stolen by the west for a long 23 years, and we were devoid of capital for investment after 1971.
Our share during the last forty years could have gone down to less than 20% vs 80%, had we remained with west Pakistan. I propose we better do not compare about our two economies, because it will only bring about our sad memories how we were exploited by west which was poorer in 1947 and richer in 1971.
You go up and be a new Japan, we do not care. But, we are happy to do our own business without an interference from you. Only future will tell which of the two countries will develop faster.
There was no Bangladesh in 1970, only Indian trained Mukti Bahini terrorist destroying East Pakistan followed by an Indian invasion in 1971.
So my Bangladeshi brother, I'll ask you for the second time, what was the Bangladeshi/Pakistani GDP in 1972-1975 and what was it in 2013? Was the gap bigger in 1972 or in 2013.

It's not a trick question so con't be scared or shy to speak the truth my brother.
