What are the countries where 1 US Dollar is enough for one times food?
In many countries that are in the South East Asia, one US dollars can get you enough food for one meal. In Malaysia, there are two days in a every month, that if you go to a buddhist vegeterian stall, you can get free meals and you just need to donate some money. Any country that has a weaker currency denomination would really have a high chance that things would cost alot less.
In Malaysia, one USD is now currently RM 4.18 which used to be 3.25 like that. Regretting to have any USD when the Malaysian ringgit was alot higher. Alot of outside tourist who come to Malaysia and especially my city would feel like a rich dude. But for countries which are neighbours to Malaysia, like for example, Vietnam, Thailand, Indonesia and the Phillipines, you can get loads more food with only USD 1. Even in some parts of China which are more rural relative to those which are in modern states, you can definitely get something for a cheaper price.
USD 1 is still worth alot at this point of time.
