I mean, there is a lot being put but this isn't the path to good policy. Good policy is arrived at slowly, thoughtfully and with people who are engaging the part of their mind that handles executive function. Usually with some compromises.

"A meat processer killed a 16-year-old. Yet US lawmakers want more child labor" is very much not a headline chosen by someone who is aiming for good policy. It is a clear ploy to get an emotional response. There are two topics that are reliably used for that - the first is protecting children and the second is war and combat metaphors (after thinking that, I read 'combat' in the 2nd link with a certain ironic smile).

The world is a very harsh place, and a lot of people are going to suffer through it. Blanket banning people from working - even 16 year olds - is unlikely to get to the best place. There are a lot of young people who's best path probably was working very hard at a job to get away from their families. Issues like that should be considered at length - and calmly. Just because the idea doesn't sit well doesn't mean it is a bad one.
