Sometimes children think they're being punished if you remove something. Especially if the parent's favored punishment is to take a toy or privilege away. I'm not defending either side here, but what the artist is doing is a tried-and-true method for pretty much every child, everywhere. Also, these kids can't communicate like you and I can. Little Ones cry, particularly if they're under 5. It gets them the attention that they want, and it often accomplishes their goals. It doesn't mean that they're spoiled, necessarily (though they can be), it can mean any number of things. I would assume that a lot of these children are more hurt and confused than anything. There's one little girl who looks particularly confused to me, but I don't know her, so I could just be projecting the faces that my niece gives.
