Total 30 billion or more we lost to Indians. No country can develop with such a nice neighbour. (Sarcasm)The usual AL supporter and Sanghi pa-chata Bangladeshis will doubt your prediction, but I fully agree.
Consider this. Out of every 15 Billion USD of remittance coming into Bangladesh from our mehnati people overseas, who clean toilets and sweep streets for a living - about $10~$12 Billion goes back to India (mostly harami chashmkhor non-Muslim cow-belters) which they then use to fund their Muslim oppression campaigns in BIMARU states.
We are employing these suwars in Bangladesh and funding all their chest-beating and minaret-climbing.
