One destroyer of that type bought = investment in about a thousand garment or white goods factories
= investment in five hundred or so software development companies
= investment in hundreds of miles of road or several port infrastructures
= one hundred thousand new jobs (direct); five hundred thousand hungry mouths fed (indirect)
= one thousand schools built to educate our young people (Bangladesh is a young country)
But you can of course fantasize, that doesn't require money. At the end of the day you have to look at reality.
