ELI5: Explain Like I'm 5

Dual Income, No Kids

"Okay kiddo, so you know how mommies and daddies sometimes work to make money for their family? Well, sometimes there are two mommies or two daddies who both work and make money. This is called dual income.

Now, usually, when a mommy and daddy have kids, they have to take care of them and spend money on things like diapers, food, and toys. But when there are no kids in the family, the two mommies or two daddies have extra money to spend on themselves.

So, dual income, no kids means that two adults, who both work, don't have any children to take care of. This gives them more money to spend on things like vacations, fancy dinners, or nice clothes for themselves. It's kind of like having extra money to do the things you want without worrying about spending it on kids."
