You're absolutely right that you can sometimes take a parent's willingness to leave a young child unsupervised as an indication of worse general parenting, but the problem I have with your statement is that I don't think that indication is enough to draw any conclusions from. There are other reasons that a parent might leave their child unsupervised and you have to give them the benefit of the doubt that their reason is o e of those. Benefit of the doubt doesn't mean that you can't keep an eye out for other signs that theyre inadequate parents, or even that you can't go out of your way to investigate, but drawing those conclusions prematurely contributes to, and might even be the driving cause of the trend towards the oppression of children that we see today. Maybe you agree with this already, but it wasn't clear in your comment.
