Impacts on America

Toll revenue of Panama canal, Nov 25, 2019, Statista
Was it worth it? For the United States, the Panama Canal was a worthwhile investment. If it cost $375,000,000 to construct, even the revenue out of one year with the Panama Canal in the 21st century would outweigh that cost. Although the labour costs were heavy, in the long term, the trade opportunity the Canal provided to America allowed the US to become a world power.
