Our national consuming power obviously de- pends upon the national income that produce. National income finances our buying power. all there is, there isn't any Our problem increase national income. Everybody agrees PRIMING that. The question is: How? Pump Priming? Government Business? Shorter Working Hours? Slowing Down Machines?

Based the rate which increased our national income during the years preceding 1929, should well over billions dollars now, terms 1929 dollars. had that much annual national income, our troubles would over. could away with relief, put all the unemployed back private jobs, balance the budget and be- gin pay off the national debt. BILLIONS PLUS can boost national income where belongs? Now I'll ask one. Why not the way did between 1899 and did then investing time savings. Time savings made possible increased productivity. And that, turn, made possible, improved methods and improved machinery. Consider for moment two workers. One 1899 and one 1929. Little difference there between them except for the mustache. Using the same tools, the worker 1929 could not produce bit more per hour than the worker 1899. And not much week, because shorter hours. When you stop think that, isn't evi- dent that time saving methods and better tools alone made possible greater individual producing and consuming power and, hence, greater national income? | _ A J METHODS BILLION AND MACHINES NATIONAL INCOME METHODS POPULATION AND MACHINES course there was larger population 1929 than and therefore more workers. Sixty per cent more fact. And per cent more people ought create per cent more national income. Adding per cent the national income 1899 and then de- ducting per cent for the shorter hours worked 1929, get national income $52 billion, terms 1929 dollars. This what our National income would have been 1929 instead $82 billion, the workers 1929 had used the same methods and the same tools did the workers 1899.

There was nowhere else for come from. That former and now forgotten national policy encouraging time savings and promoting efficiency and productivity was responsible for the steady gains wages, living standards and general prosperity which took place between 1899 and 1929. HAT has happened, since send back the 1899 income production level? Private enterprise, far management concerned, has not altered its attitude toward time savings. values efficiency highly ever. But what has been able accomplish time saving since 1930 has been more than offset time spending. For this new national policy spend and spend has affected time savings well money savings. have had past depressions and have come out them new heights national income and prosperity. But, then, there was thought throw- ing time savings overboard. fact, sought them more energetically than make for our losses. Nowadays, are spending time savings faster than make them. That's are back the level. DEPRESSION OWADAYS forces that were unknown before 1929 are work devouring and off- setting time savings. dozen them and any one capable eating our time savings fast they are produced. Take, for example, legislation limit working hours. may surprise you know that all gains efficiency and productivity per man— other words, all time savings made since been completely offset just our reduction working hours per week. The average annual gain national income production, above that due population growth, was |.3 per cent per year for the 30-year period from 1899 1929. This the rate elevation the American standard living during that period. addition that, reduced working hours the rate per cent per year. The productivity gain |.3 per cent was above this. Since 1929 have reduced working hours the rate per cent per year, not counting the reduction due unemployment. have reduced them from with further reduction manda- tory law. net retrogression 0.7 per cent per year time saving, just from this one cause among many. € > | f > (a — BS | { ) IME savings, this day and age, are most com- monly produced the use power and im- proved machinery.
