Society giving young children books before starting school seems like a good idea. Because the cost for a few books is almost nothing compared to the total cost society pays for a childs edacuation. Also parents don't read bedtime stories only because lack of money but also lack of reading tradition in famillies. That if your parents didn't read for you, you may not see the need to buy books and read for your child. But if you get a book for free to read to you and your child you may try reading for your child and found out it's fun for both you and your child. Also bedtime reading seems to have great benefits to both children and society so it probably takes a small amount parents starting reading to their children for society to get back the money.
