+1. You stumbled into the truth. In the U.S., agriculture produces a steady 10%+ return over many time horizons (10 years, 20 years, 30 years, etc.), with very low volatility. Agricultural land produces an income that beats every other investment over those time horizons, including the stock markets.
Plus people always need food, so there is an extremely low risk of any type of sanctions on food. Even if sanctions apply one day, so what?︀ The locals will eat your food. Exports are simply a bonus.
Like I said, agriculture︁ produces a steady ten percent return in the U.S. But if you build a farm︂ in Latin America, where agricultural land costs 50% to 70% less and labor costs 80%︃ less than in the U.S. -- well, I will let you do the math. Farms︄ are a dynamic cash cow with low volatility. But there is a big learning curve︅ to do it right.
