Good ideas scale. They don’t take a lot of money to become a hit. You can throw mass fortune, and resources into a bad idea and it will fail.
Look at the 2016 election. Hillary out raised Trump close to 2/1. She had rockstars Barack, and Michelle Obama campaign for her, and she failed.
A strong idea will beat a mass fortune any day. You don’t have to be a millionaire entrepreneur to have the next big thing.
