My impression comes from many many years of walking through business and looking at what people actually do when executing the processes designed to fulfill a customers' needs.
Well, sorry to come off so poorly, but people tend to use individual ancedotal evidence to come up with economic theory and apply it on a nation-wide scale, which is exactly what you have done.
Your definition of productivity and mine are exactly the same. It's a measure of the ratio of input to output. If everyone is sitting around on their hands, nothing becomes output. Well, you might be witnessing some lazy employees somewhere, and they do exist, but in relative terms, Canadian workers rate very highly when measured.
As to "I'm not an expert but..." well, I am sorry if I flamed away, but everyone likes to think of themselves as an economics expert, regardless of their vocation. It's tiring for those of us that actually earn our living in the field, as people fail to realize the worth of our knowledge and expertise, well, because "everyone knows how it really works" based on their own observations.
So is having half your workforce doing tasks that add no value to the final product, a condition that exists to a frightening degree in both manufacturing and service industries.
This statement is based on some limited observations and not on industry and nation wide standards and measures.
Let me ask you why we've had an literal economic boom for the last few years, and except in Alberta, the rate of unemployment has not falled dramatically? Everyone loves to bandy about the term "jobless recovery" like it's something we don't understand and can't do anything about. It's thanks to rising productivity in labour that has outsripped real GDP growth. Alberta has "suffered" lower unemployment thanks to the labour intensive natural resources sector that has had gains in productivity, but at a lower rate than growth in the sector.
I'm working right now with an aquaculture business that has farms in BC, the US, and Chile. Canadian processing workers are paid $15USD an hour and Chilean workers $3USD per hour. So, they started a plant and farm in Chile. Well, it sucks. The labour might be cheap, but their productivity is terribly low, quality control is awful, gov't standards are non-existant, and the education level of the worker is very low. Granted, these are not rocket scientist jobs, but they do require some degree of skill. People are operating $600,000 machines. They are probably going to close the Chilean plant and open their newest plant in Canada. Sure, labour costs are higher, but the overall productivity of the workers is amazing. In the seafood business, we're right with Norway, which has a huge aquaculture industry. Guess what? Norway kicks ass in the business, and pays their workers $23USD an hour. Hhhhmmm.
The CEO of a major food firm had bought into the "Canadian worker is low in productivity" myth and it's going to cost them a few million to learn that it's plain not true.
One thing that we must do is look at policy to harness this productivity and make it work for everyone, not just a few. During the 1930's FDR was presented with a plan to drop the work week to 32 hours in an effort to restore employment by distributing the work over a larger number of people. He nearly went for it, but copped out with the New Deal. It would have failed, but he was bailed out by WW2 which soaked up all that excess capacity.
Why do we fail to account for huge gains in productivity in the last 20 years? Why do business lobbies win out over economic theory? It's because business has convinced many people that "what's good for business is good for the nation." Well, some of it is but a great deal is not. Concentration of wealth, power, and monopolization are great for business, but really suck for the citizens.
If we were to deal with gains in productivity by redistributing the labour, we'd see unemployment rates fall. I don't know a single employer that wants that. That means the possibility of rising wages due to increased competition within the labour force. Okay, so here's where people get out their economics knowledge and talk about rising wages and that nine-hundred-headed dragon: inflation. Hhhhm. Yes, inflation is bad, but at what level? There is sound theory that we can operate a full capacity economy with 3-4% unemployment and have 4% or so inflation. Is 4% vs. 2% worth putting hundreds of thousands of Canadians to work? I think so. Look to Alberta. Thanks to friction in the oil patch labour market, we've had low unemployment and manageable inflation.
