If I am not wrong the only available fast food outlet in Bangladesh is KFC and Pizza hut . When foreign companies come inside a country they look for markets that will be much more profitable for them . That is the exact same reason why there are none in Somalia and Chad .
I never said Pakistan was first world nor is it that way infact we have a long way to go to be one . As for world bank figures .

I gave you the GDP per capita figures its pretty evident who is ahead . There so many Indexes which I can quote where Pakistan is ahead by some Distance like Food Index , Corruption Index , Economic Freedom , Mercer Quality of Life , Wealth per capita , Logistics Index . I can keep on quoting them .
US and Mexico's Homocide rate is worse than BD so BD is better i guess ? Despite you performing better in Peace Index we get much more tourists , host more International Conferences and much more Well known people from around the world regularly visit Pakistan .

We don't have the 2017 figures for Pakistan but in 2016 according to Atlas it was $1510 for Pakistan and $1330 Bangladesh . Unless you grew at 30 % there is no way that happened . Stop believing those government figures of yours . Even if we go by them its still not ahead
