You feel the energy soon after disembarking at Hazrat Shahjalal International Airport in Dhaka. All of Dhaka, the capital of Bangladesh, seems to throb with bustling masses of people. Bridges, expressway overpasses, and major new neighborhoods are continually under construction. Evidence of the country's rising disposable income is on display at crowded shopping malls such as Jamuna Future Park, the largest in South Asia, and new billboards, which seem to cover every available space, advertise products as varied as packaged foods and smartphones.
