India is perfect for global economic growth in general. India has a massive population that has massive consumer needs.

However, they cannot produce everything all by themselves. Partly because of mineral resources, partly because of education and partly because of land crunch.

Which means, when they industrialize more, they need to import more.

Which aids growth of countries exporting to India.

USA used to play that role until recently but cannot take it anymore for various political and non-political reasons. If anything, most of the developed world should be very happy that India is developing the way it is because it aids their own industries.

African countries will get there some day as well, but they would do much much better by having a unified bloc like EU.
