At least in theory, once the loss due to lack of sufficient number of workers exceeds the cost of raising the wages they should go up and at the cost of margins or increased prices. This should offer nobody a competitive advantage because every farm is likely facing the same issue. Sadly employers behave like raising wages was not even an option. I guess that's human nature - money going from you pocket is a more tangible expense/loss than money not going into your pocket due to lost profits/opportunity.
