I found the graph at 10:55 to be especially interesting because it shows how someone with around the median income ($65k) can make it to the lower upper class by retirement through some discipline (10% saved per year).

As a quick TL;DW, here are the median incomes, net worth, and percent of population for each class:

• lower - $34k income, $3.4k net worth (many are negative) - 25%
• middle
  • lower - $44k income, $71k net worth - 20%
  • middle - $81k income, $159k net worth - 20%
  • upper - $117k income, $307k net worth - 20%
• upper
  • lower - $189k income, $747k net worth - 10%
  • upper - $378k income, $2.5M net worth - 5%

Some questions to spark discussion:

• Do you agree with his breakdown of the economic classes? Why or why not?
• What strategies do you think someone in each category should take to improve their situation?
• If you don’t mind sharing, what class do you think you’re in, and does the breakdown match your experience?
