So many comments just focus on DINK being selfish but there are good reasons to not have children and I agree there needs to be better incentives, and barriers removed too.

Here are just a few reasons to not have children that may not have to do purely with selfishness. Many of these may not come up in casual conversation. It is easier to look selfish and say you prefer to keep the money and spend it on yourself for fun than going in the details of things like:

- "not wanting to do that to your body" can be more than concerns about appearance. Even if survival rates for mothers is much better, there are still plenty severe injuries and side effects to deal with. Plus among my relatives, I have yet to find a woman who didn't suffer from medical violence during her pregnancy or when giving birth. This wasn't talked about among women until they were pregnant not so long ago, understandably knowing what to expect can make it much less appealing.

- same thing with expectations about what parenting is like. Parents are more open about struggles, or regret. Even if they don't regret their kids a good number I know said if they could go back, though wouldn't have their kids even if they love them. Add to this social pressure to parent a certain way, non parents being quick to judge etc.

- some folks dont want kids because they don't think they can afford it despite having two incomes, or consider that their income would severely drop if one parent has to stop working to care for the kids, making it unaffordable. They want to give the best to their kids, so they delay forever or accept they won't ever be in a good enough place.

- some people wouldn't be good parents and know it. I've talked to enough childfree women, and many felt obliged to have kids but didn't because their own mothers were resentful parents, which resulted in a traumatic childhood.

- some want kids to care for them when they're old but see elders being left to fend for themselves or forgotten in abusive retirement homes - they may decide even with kids there's no guarantee so why bother?

- some maybe tried and couldn't conceive until they found it was too late, or couldn't afford medical assistance, or lost a child during pregnancy and couldn't bear to try again.

- some may not think their genes are something they should pass on, or don't feel the need to pass on their own genes.

- Some may have cared for sibling/cousins/nephews and know they wouldn't make good full time parents but would be ok helping others as part of "the village".

Being a DINK also has disadvantages, like constantly being expected to pick up colleagues workload when they have parenting demands during work hours, not getting nearly as many benefits (at least where i work), feeling like your free time is a free for all for anyone to take outside work because you don't have kids, so it's assumed that you have nothing going on in life. Like, feel free to ask and I can help but you don't have to be so callous about it.

I see it can be hard to have compassion for each other, if each thing the other should just deal with the consequences of their decisions. I read several posts pitching DINKs against parents over income distribution. If anything, it should be all of us parents and non parents against a system that favours a handful of extremely wealthy people.

ps: also let's try to make parent's lives better instead of saying DINK have it too good. Surely we can work to make everyone equally happy instead of making everyone equally miserable...
