It’s been a rough year for most commodity prices, but international investor Jim Rogers thinks the long-term bull market will resume apace.

Why? “Well, there’s been a huge dearth of investment in productive capacity for 30 years now,” he tells Forbes Media Chairman Steve Forbes.

“The last lead smelter built in America was built in 1969. No gigantic elephant oil fields discovered since the 1960s. I could go to agriculture.”

Indeed, the United States has a shortage of farmers, Rogers says. “More people in America study public relations than study farming. We have no farmers,” he says.

But Rogers believes that will change. “You cannot eat press releases. It [farming] has been a horrible business for 30 years. Prices have to go up a lot, or we’re not going to have any food at any price.”

American wealth is going to shift from the financial sector to the agricultural sector, Rogers says. “The stock brokers are going to be driving taxis. The smart ones will learn to drive tractors so they can work for the smart farmers,” he says.

And what will farmers drive? Lamborghinis, he says.

Debate has raged in recent days about whether gold’s 11-year ascent is ending. Morgan Stanley analysts don’t think so.

“We think gold prices will recover in the coming weeks,” they write in a report obtained by Barron’s. “The fundamental factors that have driven the gold bull market of late remain very much in place.”
