What policy did most americans embrace immediately following wwi?

Isolationist policy.

When the war ended in 1918, the United States returned to its Isolationist policy and renounced to its alliance with Europe, even enacting restriction to limit its immigration, and refused to join the league of Nations, an international organization, first proposed for the current American President Wilson.

Instead, The United States intended to focus more on domestic issues, by supporting business growth, promoting industrial expansion, imposing tariffs on imported products, etc.

hello there!

the graphics that you have attached within the question, indicates that few people in bolivia work in industry according to its labor force.

however, the graphic that is on the right side of the picture shows the gdp sector in bolivia. this gross domestic product is a macroeconomic magnitude   that shows the monetary value of all finished goods and services within a country's borders in a specific time period. in this case, the graphic is showing the monetary value in each sector -agriculture, industry and services- of bolivia in 2012.

so, although the first graphic located at the left side indicates that not so many people work in industry, this is the second most important sector according to the gdp metrics because of the monetary value that impacts on its country. it does not need to be the most valuable one. if it makes an impact on the country's economy, it will be definitely crucial to it.
