Why there's no reason to worry about robots stealing American jobs

From Carpe Diem:
"Some experts now believe that computers and robots will take over much of the work performed by humans, raising critical concerns about the future of jobs," frets MLive business writer Rick Haglund, in his article titled "Will we live in a world ruled by robots and computers, and fewer jobs for humans?"

Let me ask a related question: Isn't that just a new, recycled version of the discredited philosophy of the British Luddites – the textile workers who protested in the 19th century against the introduction of new, labor-saving textile machinery during the Industrial Revolution because they were afraid that the new machines would eliminate jobs?
Jarrett Skorup of the Mackinac Center addresses the neo-Luddite fear of robots in his article: "Robots Are Good." Here’s an excerpt:
When this country was founded, approximately 90 percent of people worked in agriculture. By 1900, growing enough food only required 40 out of every 100 workers. Today, fewer than 2 percent of U.S. workers feed not just America, but many more people all around the world.
The massive increase in farm productivity is purely due to technology. Farmers used to harvest grain with a sickle, but then came Mr. McCormick's reaper, followed by motor-driven tractors and combines. More recently, chemical and biological advancements have greatly increased yields. With each advance, fewer workers were needed to grow food. To cite just one example, today American farms produce five times as much corn on 20 percent less land than 70 years ago. 
And yet the loss of all those farm jobs did not produce 88 percent unemployment...
