Non sensical gibberish aside ..... BD growth will be propelled by a mixture of internal dynamics and international trade as it has for the last 30 years.
BD has the lowest debt ratio in the region and extremely conservative fiscal policy. Paradoxically it has a liberal outlook to international trade and has sought to foster self-reliance.
This has lead to the what is known as the BD paradox where BD has been able to expand internal capacities thereby improving on education, child mortality, life expectancy, medical coverage, social security, etc but GDP growth have not matched that of similar nations.
Economists now believe that foregoing GDP growth for internal capacities was a good thing in the long run as this will allow BD to break the middle income trap. Most middle income economies apart from petroeconomies grew by attracting export orientated FDI and borrowing heavily. This grew the GDP but did not raise up the population. The profit was repatriated and borrowing needed to be serviced creating a situation where the economies were unable to raise their human capital enough to graduate to a developed economy.
The endemic lethargy of BD government decision making has resulted in a happy outcome. As slowly BD economy has ratcheted up its human capital development has kept pace thanks to the world's largest NGO network.
BD will be able to leverage these advantages in the coming decades. Every prediction raises BD higher up the global scales in a couple of decades. Our fundamentals are good, with careful management there is no reason why BD should not be able to fulfil its potential.
