Adam Smith once earned more than $200,000 a year. Now he's unemployed and living on food stamps. YouTube/MillionDollarCupOfWater A former executive of a medical device company says a video of him bullying a Chick-fil-A employee has destroyed his career.

Adam Smith once earned more than $200,000 a year as the chief financial officer of Tuscon-based Vante. The married father of four is now unemployed and living on food stamps three years after his videotaped rant went viral online.

In the video, Smith berates a Chick-fil-A employee for working at a company that supports anti-gay organizations.

"Chick-Fil-A is a hateful corporation," Smith said. "I don't know how you live with yourself and work here. I don't understand it. This is a horrible corporation with horrible values. You deserve better."

At the time, Chick-fil-A was facing a huge public backlash for its financial support of anti-gay groups and for the company president's remarks against gay marriage.

Smith was promptly fired from his job.

"I got into work and the receptionist, the first thing, big eyes, 'Adam, what did you do?' ... she said, 'The voicemail is completely full, and it's full of bomb threats,'" Smith told ABC News.

After losing his job, Smith and his family lost their home and moved into a RV. He thought he was turning things around when he found a new CFO job in Portland, Oregon. But that didn't last long.

He was fired after two weeks, when his new boss discovered the Chick-fil-A video, according to ABC News.

Since then, he has been honest and upfront about the video in job interviews. But that hasn't been working for him, either. He's still unemployed.

Here's the video that ruined his career:
