I somewhat agree, with the caveat being when your citizens do it, you're stuck with the poor behavior because they have rights to be on the soil. You get another chance to do better when their kids become adults (and either choose to be childfree [1], or become parents, but hopefully engaged and active in the effort). When immigrants do it, you have options, because depending on your residency model, you can ask them to leave if they are not adhering to your systems designed to lead to desired outcomes. You can treat people well and they still don't perform to expectations. Broadly speaking, you don't want an endless obligation of having to provide material amounts of support and services (which comes out of the pocket of taxpayer citizens) to people who don't give AF, but we should be accepting of inevitable drag when people did try and still fail (such is life). It's a poor outcome for everyone involved imho, but accountability is very important in the context of child rearing.
