Mike Maples:

Cornelius Vanderbilt did not say, “I want to replace the stagecoach.” Thomas Edison didn’t say, “Death to kerosene and whale oil lamps.” Henry Ford didn’t say “No more horses and carriages.” The stock market was a new thing that helped entrepreneurs create new businesses that advanced the standard of living. Abundance happened because ambitious people were looking forward and trying to make new things that were exponentially better.
 150 years after the first railroad IPOs, the US stock market alone is worth more than $30 Trillion.
