While demand for locally-grown produce is growing, increased labor costs have resulted in labor-intensive fruit and vegetable production shifting from the US to Mexican farms. The issue has been exacerbated by recent waves of xenophobia, decreasing illegal immigration, and an existing worker population that is aging. The labor supply is decreasing while agriculture related jobs are increasing, resulting in a worker shortage and production slowdown that many have not anticipated. Many farms cannot afford to house farm workers where the crops are grown, and as labor costs and housing costs continue to increase, the prices of high value crops will be forced to increase as well.
