1931: America is in the midst of a severe economic depression, known as the Great Depression. Led by President Franklin Roosevelt, the federal government proposes and implements a series of social programs known as "The New Deal."

Today: The country benefits from a robust and growing economy. Although there is still a wide chasm between the well-off and poor segments of society, most people enjoy low interest rates, low unemployment, a booming stock market, and cheap and accessible sources of fuel.

1931: Most Americans travel by train or ship. Commercial aviation is very limited, and cars are becoming more popular and financially viable for the middle classes. This improved mobility allows people to move from the cities into surrounding suburbs.

Today: Most Americans travel by car and airplane. Airline price wars decrease airline fares, allowing many Americans to travel frequently and cheaply.
