McDonald's marketing practices to children are controversial and raise questions about their corporate social responsibility. Critics argue that McDonald's uses deceptive marketing like toys to influence children to nag their parents into buying fast food, which can negatively impact children's health. However, McDonald's maintains that it is up to parents to decide what their children eat and that they are just providing options. Overall, there are valid arguments on both sides about whether McDonald's practices are ethical when it comes to marketing to children.
