Where does America derive her wealth? From the military. At the end of the day, all money is just based on military prowess.
Therefore, a thought; maybe, if you want to become really really rich, or build your wealth, do more things with the military?
For example, note Lockheed Martin, Boeing, and companies and corporations which supply the military with stuff?
Even random things; how Bose has special noise canceling headphones for the military
Or, how my brother-in-law’s friend created special energy drinks for the military?
Also in photography, does Nikon supply the US military with cameras?
