Marie Antoinette has a very famous line "Let them eat cake" related to the food
crisis in France. Why do the people of
France have no food?

Poor taxation on the upper class.

Explanation:

The French typically taxed the lower classes 90% of the government's taxes, while the middle and upper classes typically only had to pay 10% of those taxes. Though, the lower class who were depended on the taxes were barely working and had very bad living conditions.

Due to these poor conditions and heavy reliance on a class that could not fulfill these wishes, food shortages occurred due to the lack of money coming in. The lower class could barely live for themselves so it was out of question that the lower classes could aid with taxes.  

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.
