  • At the start of the school year, assume that 1000 students show up. In the first month, the slumlord converts 900 students into money

  • In the next month, there are only 100 homeless students left, so the slumlord can only convert 90 of them into money

  • Finally, in the third month, there are only 10 students left, resulting in a very small velocity of $9 produced for the poor slumlord
