The expression "in an ideal/a perfect world" is used to describe a situation or scenario that would be perfect or ideal, but may not be realistic or practical in the real world. It is often used to express a desire for something that is not currently possible or to contrast with a less than ideal situation. For example, "In an ideal world, everyone would have access to affordable healthcare" or "In a perfect world, there would be no hunger or poverty."
