Soon after the Constitution was ratified in 1788, the first Congress passed the first patent law in 1790 to encourage Americans to invent useful devices,<ref>http://inventors.about.com/library/weekly/aa073100a.htm</ref> and ever since Americans have been doing exactly that.  The inventor makes money for himself because no one else may copy his invention for 17 years without paying him for it, and the public benefits from how the inventions save time and money in performing necessary tasks.

Within a few years of the ratification of the U.S. Constitution and enacting of the first patent law, Eli Whitney invented the cotton gin, which was a machine that replaced hard labor of 50 men to separate cotton from cotton seeds.  He received a patent (exclusive ownership) for his invention in 1794.  Whitney became wealthier due to his creation as people paid him for the right to make and use his invention; southern plantations became wealthier from his invention because it reduced their costs; and the entire public became wealthier because the price of clothes containing cotton decreased due to the lower costs.  This is how an invention creates wealth for the world.

Several of the most important inventions concerned communications, which created wealth by reducing the costs of exchanging information, and increasing the amount of information available.  In 1831, an American scientists named Joseph Henry invented the first electric telegraph, which enabled communication across distances by using codes to represent letters.  Soon thereafter, the American Samuel Morse created Morse code to standardize the codes used (1835), and then in 1843 he invented the first long distance electric telegraph line.  This enabled the sending and receiving of messages almost instantaneously over long distances, without having to wait for someone to travel the distance.  Obviously this greatly increased the ability of people to communicate with each other, and for businesses to communicate their needs and purchases.  This was not like the internet yet, but it was a tremendous improvement over sending letters by U.S. Mail, which could take weeks if the distance was long.  The Pony Express was not even available then; it was first established in 1861 to try to speed up mail delivery.
