David's Time With Peter F. Drucker 2020.4.4
Of these four 20th-century growth sectors, Government probably has the greatest impact on the distrubution of disposable income. Not because it is a major buyer or user of products and services; except in wartime even the biggest government is only a marginal consumer. But the main economic function of government in a developed country is to redistribute between 30 an 50 percent of the country's national income. Nothing else has therefore as grent an impact on the distribution of shares of national income as changes in government policy.
The other three——Health Care, Education, Leisure——are all major users of products and services, that is, of material goods. But none of them provides material, and that means “economic,” satisfaction.
And all four are not in the “Free Market,” do not behave according to the economist's rules of supply and demand, are not particularly “price sensitive” and altogether do not fit the economist's model or behave according to the economist's theories.
