In this chapter, Gladwell dicusses the adavatages and disadvantages of having to much or to little of something. He uses an upside down porabola, called a U-Curve to explain his point. He uses examples partaining to classroom sizes and a person's wealth.
With smaller classrooms there is less of a diversty in between the student which may equal to less interruptions during educatinal time. While having larger classroom also has its down falls. Larger classrooms tend to have a large diversity of people who tend to interact amongst themselves which may cause educational disruption.
Many may say that extreme wealth can make anyone happy but that may not always be true. Gladwell demonstrates having too much wealth while raising a child is rough due to the child having an abundance of every thing and lacking nothing. This may make a child not see the apporpriate value of anything and cause a lack of understanding of the "real world"
