(The image above is a map of the administrative districts of Paris. The prevailing wind in Paris is the southwest wind, so the wealthy districts of Paris are in the southwest corners with good air quality, including the 7th, 8th, 15th, and especially the 16th district where the nobility and high-ranking officials gather. The poor can only live in the northeastern corners where exhaust gas and smog are concentrated, with the 18th, 19th, and 20th districts being the most obvious. The housing prices and cost of living there are also cheaper.)
Eric's aircraft factory is located in the 20th district of Paris.
The 20th district is a poor district, and Eric thought that setting up the aircraft factory here would allow him to hire low-cost workers.
However, the reality was: if he couldn't sell even one airplane, he wouldn't be able to afford even the cheapest workers.
