As Mexico is not going to pay for “the Wall" as originally promised, the president and Congress have become entangled in a battle to find funding.
Here is an idea. Stop subsidizing farmers to grow nothing. Allow them to grow marketable food and open up overseas markets to sell these goods. The government reduces payments for nothing, farmers go back to work, the land is productive, the world eats a little better. Funds become available for other pet projects, like the wall.
