Making Sense of "Made in the USA"
Infrastructure/Business Investments: This is private citizens' investments in business and infrastructure. New factories, new computers for an accounting department, new trucks for a shipping fleet, are all purchases that contribute toward raising GDP and are obviously things that would be influenced significantly by the presence of American manufacturing.
Citizen Consumption: Everything private citizens consume. Food, clothing, cars, dance lessons, video games, roller coaster rides, it all goes here. Manufacturing's impact here is obvious: To consume something, it has to exist, so provided there is enough demand, the more you can make, the more you can consume, and the more you consume, the higher GDP.
Government Spending: Like citizen investment and consumption, except from the perspective of the government. Manufacturing's impact is here largely similar to the prior two examples, just kept separate for the sake of understanding the government's impact on the economy.
Total Exports: Goods produced, but not consumed within the country. Separated from "consumption" since they're technically consumed outside the GDP equation, in whatever country they're shipped to.
Total Imports: The only negative part of the equation. Imports are subtracted since, though they are consumed, they are not produced within the country and thus can't be counted toward a country's product. Since the only way to reduce importing is to either consume less or make what you need stateside, American manufacturing is really the only way to improve this part of the GDP equation.
So what does this all mean? It means that, while by no means the only factor in building a healthy economy, GDP, and by extension, American manufacturing, are a vital part. It might seem obvious, but again, sometimes obvious isn't enough. Sometimes a more detailed explanation is in order, whether for personal understanding or to assist a client in product selection and purchase.
