Bush was president, and certainly a far cry from its apex of For investors in stocks and management of publicly traded companies, these have been rewarding years, as this era of lower corporate taxes has helped bolster earnings and dividends.
For over thirty years, economists have pointed to globalization as the cause for this growing disparity of wealth in the United States, as many jobs were shipped off of U. In , Thomas Friedman promoted this idea when he warned readers in his aptly named book, The World is Flat, that jobs can easily be performed in India as well as Indiana.
Nine years have passed since Friedman claimed that the U. Despite the ability to have operations anywhere in the world, the growing disparity of wealth is not a problem isolated to the U.
Brynjolfsson and McAfee give many examples as to how machines are leading to income polarization and contributing to the disparity of wealth. A task that once required a full-time bookkeeper can now be performed by someone with little accounting experience at a fraction of the cost, enabling the few that manufacture this software to reap a larger profit for themselves. It took him close to seven months to do so and was a full-time job. As the U.

For those without a college degree, wages have fallen since Those with college degrees have seen their income remain relatively flat, while those with advanced degrees have fared much better. It is this disparity of incomes by level of education that has been the most challenging for nations, as no longer is the economic tide raising all boats.
It is the double-edged sword of technological advancements that makes one wonder whether technology is good or bad.
The Luddites certainly had their opinion on the matter, but today we celebrate new technologies. For those without a college degree, wages have fallen since Those with college degrees have seen their income remain relatively flat, while those with advanced degrees have fared much better.

However, machines have not replaced all middle class jobs. To best understand how the second machine age has impacted the middle class, Daron Acemoglu and David Autor suggest that work can be divided into a two-by-two matrix: cognitive versus manual, and routine versus non-routine.
They found that the demand for work has been falling most dramatically for routine tasks, regardless of whether they are cognitive or manual.
These are the jobs that can most easily be replaced by machines and lead to job polarization, a collapse in the demand for middle-income jobs. However, non-routine cognitive jobs financial analysts, doctors, professors, architects, etc. What is evident in this second machine age is that the world we live in will require new tools for understanding and hopefully, addressing the societal and intellectual changes that technology is creating.
Brynjolfsson and McAfee point out that we need a new way to measure our G. Likewise, our economic theories are in need of an objective and honest review, as they are becoming more political platforms to preserve power than genuine attempts to improve the welfare of communities.
We also need to improve how we educate our children. Our modern economy will provide few opportunities for those who are not educated, but boundless opportunities for those who are educated and can harness machines to increase their productivity. Computers have, as a result of it, improved at speed unprecedented in the history of technology, radically increasing in power and flexibility while plummeting in size and price.
An iPad 2 from , smaller and lighter than an issue of Vanity Fair and as easily slipped into a briefcase, matched the processor speed of a room-sized Cray-2 supercomputer from It cost well under a thousand dollars.
The defining machines of the age steam engines then, chip- based computers now have reached technological maturity and spread widely through society, enabling those who possess them to do things that would have seemed utterly fantastic only a decade earlier.
The result, now as then, will be radical, foundational social and economic change.
Chapters explore why innovation in computers and other digital technologies has accelerated in the last decade and will probably continue to do so for the foreseeable future.
Spread is the downside: Our goal as a society, Brynjolffson and McAfee argue, should be to maximize the bounty while limiting the spread; the final section of the book, Chapters , contains their recommendations for achieving that goal.
They present all of it in clear, conversational prose studded with pop culture references, quotes from experts in a dozen different fields, and unexpected juxtapositions of the real and the imaginary. The authors excel at explaining complex ideas clearly.
The discussion of technological unemployment—an idea coined by John Maynard Keynes in the s—shows how the shift from a mechanical to a digital world turned it from a debatable concept into an inescapable side- effect of technological progress.
It uses the familiar analogy of grains of rice on a chessboard 1 on the first square, 2 on the second, 4 on the third, 8 on the fourth, and so on , but draws an unfamiliar lesson. The thirty-second square, the authors note, holds a relatively comprehensible 2 million grains of rice. The same eye for unexpected interpretations and telling examples is evident when they break new interpretive ground. Kodak, created in an age when photos were emulsion-on-paper objects, employed over , people directly a third of those in its Rochester, NY headquarters alone , and supported thousands more who were part of its network of dealers and distributors.According to a July story in the New York Times.
Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar. Skip to main content. As Weitzman writes. Both could also take still photographs, and the back camera had a 5x digital zoom.
