Ideal usually refers to something that is considered to be suitable. For example, it will be ideal to live in a world wherein no one is experiencing poverty. This is a perfect world, but it does not mean that it is real. Real refers to what is truly happening right now. Real means that there are a lot of people all over the world who are going hungry because they do not have enough money to purchase the things that they need.
Even basic needs like food will not be available for them readily because reality does not always mean ideal. People are considered to be lucky when they can reach their “ideal” lifestyle because not everyone has the chance to do so.
