I’m pretty sure a bag of rice is way more cheaper in the countries where it is produced versus the countries where it’s exported. In some countries it’s more expensive to be poor than in others.
Put it this way, India is a relatively wealthy nation and a large proportion of middle class Indians don't have flush toilets. How can you compare that to a middle class European with a straight face?
It's not that the cost of living is lower it's that standards of living are.
