You can choose not to have a child (though caveats around carelessness apply). You kind of cannot opt out of parenting once you have a child. Not if you wish to remain a decent human being. It's kind of forced on you, even more so than a job, because it's much easier to change jobs or just go on a welfare than to stop doing all the parenting each day as a parent throws at you.
