The number of Amish in the U.S. has doubled since the 1990s.

Though they're typically known for for their traditional, family-based Christian values and austere lifestyles, there's one thing most people probably wouldn't guess about them –– the Amish are a lot better at managing their money than the rest of us.

"Some Amish do quite well and have a lot of success in business," Erik Wesner, founder of AmishAmerica.com, told us. “An Amish millionaire is not something unheard of.”

Their business and financial savvy goes far beyond rebuking modern conveniences like electricity and technology.

We asked Wesner, along with Lorilee Craker, author of "Money Secrets of the Amish," to let us in on how the Amish have mastered their money.
