To turn one job into two jobs, split it in half and have each worker work half-time. Welcome to socialist economics. From Jeff Thomas at internationalman.com:
Economics should not be an especially difficult subject to understand. In essence, it’s simply the study of how money functions. However, academics, theoreticians, politicians, and financial leaders all stand to benefit if they can manage to complicate the basic principles and muddy the waters of economic comprehension.
No individual has been manifestly more successful at this than the economist John Maynard Keynes. Educated at Cambridge, a bastion of Socialist thinking, Mister Keynes famously published The General Theory of Employment, Interest and Money in 1936, forever changing the world’s perception of economics.
This was quite an amazing feat, especially as Mister Keynes’s goal was not to explain economics, as had traditionally been the object of the subject; his goal was to distort the study of economics—to confuse economic principles in order to promote socialist concepts.
Socialism had, since its beginnings, been unpopular with many people, as it clearly did not work economically. So, in order to make socialism more broadly acceptable, Mister Keynes, in his book, suggested essentially that, although 2 + 2 = 4, with socialism, 2 + 2 could somehow equal 5.
