Colonial hang ups. Worth, progress, modernity is all judged by the yardstick relevant to the white man and the burden it left on our collective psyches.
Also, when everyone around you has just as bad of a grip on the English language (grammar, vocab, spoken --- everything), then you start feeling like yours is fine.
The countries that are today not superpowers but are very relevant on the world stage (Turkey, Iran, Germany, Japan, etc.) all take exceptional pride in their local languages. All their local signage, menus, government machinery, etc., is in their local language. Yet they are more interconnected and progressive than us ---- interestingly, while occupied, none of these countries were colonized by Imperial Britain in the way we were.
Voh log jinko ye bhi bohat kamaal lagga ho ga.
When standards go down, when your top brains stop joining civ/mil forces (barring a TINY amount of exceptions), this is the result.
