Made in the USA allows you to see exactly what you are paying for as you’re able to travel to suppliers for development, management, and site inspection purposes. But the cost can be higher because of the cost of labor is significantly higher than in countries like China. Sometimes you need to go outside of America’s borders looking for suppliers with lower production costs and higher manufacturing productivity.
