In many countries — particularly in the developing world — System D is growing faster than any other part of the economy, and it is an increasing force in world trade. But even in developed countries, after the financial crisis of 2008-09, System D was revealed to be an important financial coping mechanism. A 2009 study by Deutsche Bank, the huge German commercial lender, suggested that people in the European countries with the largest portions of their economies that were unlicensed and unregulated — in other words, citizens of the countries with the most robust System D — fared better in the economic meltdown of 2008 than folks living in centrally planned and tightly regulated nations. Studies of countries throughout Latin America have shown that desperate people turned to System D to survive during the most recent financial crisis.
So what kind of jobs will predominate? Part-time work, a variety of self-employment schemes, consulting, moonlighting, income patching. By 2020, the OECD projects, two-thirds of the workers of the world will be employed in System D. There’s no multinational, no Daddy Warbucks or Bill Gates, no government that can rival that level of job creation. Given its size, it makes no sense to talk of development, growth, sustainability, or globalization without reckoning with System D.
