NPR Doesn't Believe in Markets
Those of us who believe in markets would suggest that the farmers try raising wages. It is possible that some of the crops being farmed now in California would not be profitable, if farmers had to pay the wage necessary to attract workers in the current market (or if they had to pay the market price for water). In a market economy, that means that the farmers made bad choices on crop choices.
That's unfortunate for the farmers, but that's how markets work. I would like to be able to get a lawyer for $20 an hour, but because we have a lawyer shortage, that is not an option. Maybe NPR will be able to find some folks who understand markets to help with their reporting on economic issues.
