What happens when automation is implemented is a matter of DECISION on the parts of both management and labor of a given company, and is affected by the nature of that particular company and industry. It can go a lot of directions.
This whole topic is a false dilemna that I am intimately familiar with and therefore disgusted when somebody wants to capitalize on the ingrained fears of the public by oversimplifying the problem to sell a book. I spent over 30 years as an engineer designing and implementing factory automation, and in all that time it ALWAYS resulted in MORE people being hired! That really flies in the face of what is proposed in this thread, but it is true.
What happens most often is that more goods are produced at a lower cost, sold at a lower price. The factories then grow, and employ even more people. Think electronics here, and the history of, say, calculator prices. The first commercial hand held calculator that I saw was made by Hewlett Packard, the HP-35:
http://www.hpmuseum.org/hp35.htm and cost $400--sometime in the early 1970's!! I bought one of similiar capability a couple months ago for about twenty bucks, and in the meantime, the value of that twenty bucks went down dramatically. Are fewer people now employed making calculators?? No. In fact, there are a lot more people employed making them now, but the key is, NOT IN THE US. Those who justifiably fear losing their jobs often blame automation when the real problem has been something else, like offshoring of manufacture from the US to Asia.
There ARE cases where automation reduced jobs, like the printing industry that Pops is familiar with. However, those people most often found other jobs, and continued to buy comparatively cheaper printed products, and more of them. As witness, check your mailbox for junk mail. Yes, skillsets pertaining to a given older technology get outmoded and superceded by new ones. In many cases, I was the one who trained our existing workers to utilize the new technologies, who were then more productive and soon were making MORE MONEY, and buying cheaper goods that resulted from that greater productivity. Bottom line--their standard of living went UP, and so did employment.
I don't mean to minimalize the impact on individual lives where changing technologies destroyed the usefulness of their skills. There is a painfully wrenching period of adaptation involved before those individuals can retrain and benefit from the changes. Too many times, they refuse to retrain or learn a new job, instead falling down the economic ladder while others embrace the new ways and become a part of it. Many times, a given factory is outmoded and closed, causing a blight in a given area. Other areas, however, benefit in the LONG term. The benefitted area may be in India or China, but that does not make it the fault of automation. Instead, globalization by international companies is the culprit.
Even more often, when a job is "dumbed down" by automation, it becomes something that unskilled labor in 3rd world countries could do. The jobs went there, aided and abetted by govt. policies to benefit big corporations that were heavy campaign contributors. Like GE, who has been in the news lately for this sort of thing, paying little or no taxes in their parent country.
The reasons for the improved standard of living over the past century is automation in mass production that utilizes ever greater amounts of----wait for it---FOSSIL ENERGY, instead of the sweatshop routine. We need to be concerned more about how we maintain a standard of living better than circa 1850 when the cost of fossil fuels precludes their use in such massive amounts for manufacturing, and particularly, food production.
I have only touched on a very few of the many factors involved in why people lost jobs in the US. Rest assured, automation was NOT a prime mover in that. Look instead to govt. policies, corrupt officials, major bank interests/speculators, currency fluctuations, and other sins of TPTB.
One example of the above, involving currency valuations:
In the mid-1980's, I ordered some threading taps for a sample production run at a factory. I was used to paying about a buck-fifty for them. I found a discount supplier who sold me two dozen taps for about $15 = about half price, AND he threw in a FREE 1" micrometer that had been costing us about $50. These turned out to be top quality tools made in POLAND, who has some of the finest toolmakers on the planet. But at that time, Poland was going through a horrible time trying to get out from under the USSR, and the currency of Poland was trashed. Their currency was worth zilch compared to the US dollar at that time.
Soon after that, very high quality, highly automated US tool company (Regal-Beloit) closed a plant near where we live, because they could not compete with imported tools. I doubt seriously if those directly responsible for the low value of the Polish Zlotny (?) currency ever shed a single tear about the losses to Regal-Beloit.
This is FAR too complex a topic to say that automation destroys jobs. If that were the case, why don't we still have the employment levels of the 19th century? I call BS.
