We produce wealth as we seek more efficient ways to provide for our needs and wants. While the equation of millions of people producing millions of things can seem quite complex it is really a mostly simple observation. There is a natural current to it that ebbs and flows according to demands and the subsequent supplying of those demands. As ambitious people study these principles and discover the needs and wants of society they work motivated by the fact that they can make a profit and keep it.
If you think about somethings in context of history and look at the many things we enjoy in our day and age it is almost amazing beyond belief. Twenty-five years ago only the wealthiest enjoyed the convenience of a phone in their car. This phone however had many faults and glitches as to when and where it could be used. Today almost every kid over 11 and most people on the street have a phone in their pocket. In some countries that have developed the technology to its highest level there are no dead spots for cell service. That first phone cost 5,000 dollars and dollars per minute of use. Today they cost upwards from $50 depending on the service agreement and usage is unlimited.
