Nobody here has the means to fix this problem.
It's fine to sympathize with it, as it's certainly not a topic anyone (but the slavers) supports, but to discuss care vs. fixing the scenario is pointless.
The issue is not simple enough for anything that could be discussed here to work, or it wouldn't be an issue in the first place. All of you here get many of your things indirectly through the facilitation of child labor, whether you like it or not.
On the note about caring for yourself...I agree with the standpoint of Bubbles. Look, it's terrible that this is happening but I have more important things to focus on. Like someone else in the thread said, if you just sit there and cry about every bad thing that happens on a daily basis, that's all you'll do. There isn't enough time to truly care and fix these problems on an individual basis, and you'll just stay sad all the time if you try.
