So then havent we moved on from the reason that "people are lazy and wont work as hard" to the reason that "technology has increased the ability for one person to make a lot of things very easily"?
As this study points out several key things come to mind:
Firslty productivity is defined as: "Productivity growth, which is the growth of the output of goods and services per hour worked, provides the basis for the growth of living standards"
--We not only are doing more work but working longer
And also
"First, as shown in Figure B, average hourly compensation—which includes the pay of CEOs and day laborers alike—grew just 39.2 percent from 1973 to 2011, far lagging productivity growth. In short, workers, on average, have not seen their pay keep up with productivity. This partly reflects the first wedge: an overall shift in how much of the income in the economy is received in wages by workers and how much is received by owners of capital. The share going to workers decreased."
