ELI5: Why does soda from poorer countries like Mexico and India come in nice glass bottles, while it comes only in cans and plastic bottles in the U.S.?

Every time I've seen Mexican Coke and Pepsi, it comes in glass bottles. And I've also had Thums Up at Indian restaurants that also comes in glass bottles.

Why is soda sold in glass bottles in these countries? Isn't it more expensive? Wouldn't you expect it to be the other way around: that in richer countries they would sell soda in nicer bottles? I know they sell Coke in glass bottles in some places in the U.S., but it is way overpriced compared to cans. I don't see why anyone on a budget would buy the glass bottles.

In those countries, they have bottle deposits.  Re-using the bottles is cheaper (for the bottling plants) than producing new plastic bottles that are going to be thrown away.

As for the consumer, you're right that it makes it slightly more expensive.  I've been to poorer areas of Mexico where they ask for their bottle of Coke "en una bolsa" (in a bag).  That doesn't mean what you think it does.  In those cases, the shopkeeper would open up the bottle of Coke, and proceed to pour the Coke into a Ziploc baggie, which the consumer would then drink from out of a straw.  They would do this so the consumer could collect the bottle deposit immediately, rather than having to pay it on top of the cost of the Coke.
