Sumner Slichter quotes:

The greatest danger to an adequate old-age security plan is rising prices. A rise of 2% a year in prices would cut the purchasing power of pensions about 45% in 30 years. The greatest danger of rising prices is from wages rising faster than output per man-hour.... Whether the nation succeeds in providing adequate security for retired workers depends in large measure upon the wage policies of trade unions.

If each year slightly less capital is invested in industry, the time will eventually come when the amount of equipment per laborer and, in consequence, the productivity and the wages of labor are less than they otherwise would be.

The efficiency of most workers is beyond the control of the management and depends more than has been supposed upon the willingness of men to do their best.
