More than half our people do not live on farms or on lands and cannot derive a living by cultivating their own property.

Context

“Pick up the next tragically obvious economic question—where is opportunity? We must dismiss that historic one which has heretofore been our salvation. Our last frontier has long since been reached, and there is practically no more free land. More than half our people do not live on farms or on lands and cannot derive a living by cultivating their own property. There is no safety valve in the form of Western prairie to which those thrown out of work by the economic machines can go for a new start. We are not able to invite the immigrants from Europe to share our endless plenty.” source
