Jonah has convinced Adam to buy a new grill and a new TV, but he didn’t know that Adam was married to Amy. Part of the reason he convinced Adam to purchase these items was so that his team could win the Color Wars and Amy could get a $100 bonus. While Amy and Adam are fighting, we learn that Adam is a serial entrepreneur and Amy invests in her human capital.
This scene is a good example of the tradeoffs associated with investing in human capital and physical capital. Adam wants to invest the money to support his business ideas, but Amy believes that investing in her college classes is better because it can lead to more money later.
