Not exactly as par with Japanese, but, may be at par with other people of the sub-continent. However, Indians prefer to think BD people below their esteem only because they have a big land, big military and big economy. They do not really understand that the part of which the present India is formed was a way 100 yrs. ahead of us in 1947. It had all the industries, roads, ports, big cities, bridges trams and buses, because it was the central part of the then India before 1947.
Add with it all the already built big businesses and big industries like Birala, Tata, Marwaris, Sindhis, Gujjis and thousand others. When India is improving on the facilities built by the British, we are still building the infrastructure in a land that used to be under water for half the year. However, without considering these things, the highly educated group of Indians keep on insulting BD for its all the shortcomings.
Anyway, this is Shonar Bangladesh!! We have to go a long way to answer Indian meanmindedness!!
India is not big economy when you consider how many people it has.
Per capita India and BD is similar.
