Wages for farm workers and food processing will likely rise, if the past is any guide.

How did these higher labor costs fit into wholesale prices? Here are some key PPI components vs. foreign born employment share.

Now, one could argue that the increases in these PPI components was just a symptom of the generalized increase in the price level (some would say monetary policy). However, we can examine the relative price of groceries. Here’s that picture.

Notice that the relative price of groceries started falling once the share of foreign born employment re-attained pre-family-separation trend.

So, don’t say you weren’t warned.
