Joshua Richardson's days unfold about like any 4-year-old's. His mom, LaKetra Richardson, pulls him from under his Spider-Man covers way too early every morning so she can get him and his 2-year-old sister, Alice May, to preschool and still be on time for work. At 4, he knows his letters, his numbers and what time "SpongeBob SquarePants" -- or, Spunk Bot Care Pat -- comes on. He has no idea, though, that he is part of one of the nation's fastest-growing demographics: children growing up poor.
