Farming is generally very seasonal you work very hard for long hours during harvest, but that's only two or three weeks a year. Planting season again, you work very hard for a couple weeks, but the new it's done and you just wait for things to grow. It's not just waiting, You occasionally have to get out to weed and monitor the conditions, but there's many weeks where there's little to do and no need for a farmhand.

Many farmers have a second job of some sort that they work between farming tasks.

immigration restrictions also hurt because people who are poor and would take anything and be happy with work for those few weeks can't get in. In the poorest countries, you can easily have a nice living only working a few weeks a year in the US.
