When Thomas Jefferson referred to the Missouri Compromise he described it as “ fire bell in the night”. This is because he saw it as a pressing matter and he saw this as an emergency since a fire bell at night indicates that there is an emergency.
Hope this helps! :3
As multiple nuclei develop, transportation hubs such as airports are constructed which allow industries to be established with reduced transportation costs. These transportation hubs have negative externalities such as noise pollution and lower land values, making land around the hub cheaper. Hotels are also constructed near airports because people who travel tend to want to stay near the source of travel. Housing develops in wedges and gets more expensive the farther it is from the CBD.[2]
Not sure if I understand your question completely, but if I do I believe you are talking about pensions. When people pay into retirement funds they will actually receive more in return when they are retired. Money loses value over time, hence why 5 cents could get you a coke back in the day, whereas its a dollar or 2 now. So when someone pays into a retirement fund or pension, they may be paying a certain amount now, but they will receive more because of the changing value of money.
