Still, however Indonesia has a larger NOMINAL GDP to Turkey has.
Indonesia should be compared to Pakistan, Nigeria, and Brazil from a population's perspective.

India is more prosperous than Singapore in NOMINAL GDP.

Little legitimacy from your point of view? That is just your "opinion."
Regardless of everything, Indonesia still has
a larger economy than Turkey.

And don't bring other aspects like Nominal GDP, Industrialization, export value.
Or poverty rate.
