The correct answer is: It hurt cities economically because the middle class paid a large share of the taxes. 

The flight of the urban middle class affected the suburbs because this was transition from the war that has caused many people to pay their taxes for the infrastructures that needed to be built and the supplies that needed to be sold to the market. The economy was at an all-time low as well during this period, and the government had to take action by imposing higher taxes on the masses.
