Consider the following quote from Franklin D. Roosevelt: In creating this civilian conservation corps we are killing
two birds with one stone. We are clearly enhancing the
value of our natural resources and second, we are relieving
an appreciable amount of actual distress. This great group
of men have entered upon their work on a purely voluntary
basis, no military training is involved and we are
conserving not only our natural resources but our human
resources. One of the great values to this work is the fact
that it is direct and requires the intervention of very little
machinery2
Why is the use of machinery of any concern to President Roosevelt?
