In my thirty plus years of surveying and studying millionaires, I have consistently found that 80 to 86% are self made. That also applies to decamillionaires. In 1982 according to Forbes about 38% of America's wealthiest people were self made. In 2012, the percentage jumped to 70%.
Economic opportunities abound in this country. Yet most Americans are not wealthy. It is easy to blame the so-called inequities in our economy. But it is more about the fact that Americans spend all or most of their income on things that have little or no lasting value! They lack the discipline required to accumulate wealth. Most households are on a treadmill of working and consuming.
