Question

How does use of cargo containers benefit the economy?

A. By preventing protective tariffs

B. By keeping distribution costs low

C. By decreasing pollution

D. By generating renewable energy

Answer 1

B. By keeping distribution costs low

Cargo Containers allow for the seemless transport of goods around the world. A container can go from Ship, to Rail, to Truck, to Store without anybody touching the contents.

Imagine if you needed dock workers to manually unload each widget that is imported from a ship. Then recrate it into a Rail Car.. You are talking massive labor costs and time delays  and that means $$$$ money.. Money that would get passed onto the consumer in terms of higher prices.
