California farms already hurting because of immigration policy

Fortune - Vegetable prices may be going up soon, as a shortage of migrant workers is resulting in lost crops in California.

Farmers say they're having trouble hiring enough people to work during harvest season, causing some crops to rot before they can be picked. Already, the situation has triggered losses of more than $13 million in two California counties alone, according to NBC News.

The vast majority of California's farm workers are foreign born, with many coming from Mexico. However, the PEW Research Center reports more Mexicans are leaving the U.S. than coming here.

To make the jobs more attractive, farmers are offering salaries above minimum wage, along with paid time off and 401(k) plans, but even that's not proving enough.
