@qz - here's a good one about productivity concentration.

Productivity is one thing I've wondered about as there have been huge improvements as the world becomes digital. A couple people at a startup in Silicon Valley can literally produce a product that can eliminate the work of hundreds of thousands of clerical type jobs. That's like 1000x more economic productivity once the tech/program becomes fully integrated into business.

Since 1983 US the US Bureau of Labour shows that the output per worker per hour (non farm, business) has risen by 85% and manufacturing hourly output per worker has risen by 105% since 87. Meanwhile in that same time period the participation in the paid labour force by women has risen from 50% to 60%. That's including women outside the working demographic, who are older than 20, so it's more like 70-75% of women who can work.
Basically it's like the average worker produces 2x as much, and the percentage of population working has increased by 10%.
But manufacturing, a big part of the value added production (ie tradable goods - see the economist link) has shrunken and the output relies more on software and intellectual property (and a ton on made up financial industry 'output'). In Canada we've got natural resources to buoy us up so it's different.
In anycase, we've had such tunnel vision and have directed so much effort and innuendo to educate and train people into the high earning (but low tradeable, tangible goods output) that there is a shortage of people who have a sense and knowledge of skilled labour and physical work, which is where the ever rising need is. We've really been coasting off the physical work of previous years and allowed our collective capacity for such things to diminish. But as pressure mounts we're slowly waking up to the physical realities that are required to meet our physical needs. A degree, the computer, fake money, paper money and the internet can't provide all of that. Mexicans can to an extent, I guess (probably why they were included in NAFTA?).
Anyways, somewhere along the way there has to be a collective awareness, desire and capacity created for skilled, physical labour because collective we've undervalued it and become blinded to our necessities. We're also losing hard earned industrial manufacturing skills, or our ability to capacitated ourselves with industrial production. A generation gap where built up experience and wisdom are not passed down means the learning process becomes longer.
Rant aside, we need to take away the stigma from physical work by exposing young people to it. I was only exposed to it when I started forestry work during the Summer as a university student. I got a taste for it, and it's lovely. I won't do it all day everyday all year, but my body and mind have a need for it that I now have to feed which means I have to avoid specialist work so I can keep a foot in the office world and in the more real world. I bet the same unexplored need lies dormant in millions of youth.
If the corporate financial influences hadn't managed to hijack the currency and government, money was somewhat more equitably distributed, and low level work/labour was not so undervalued to create literal slaves that have to work 50-60 hours a week for subsistence level lives then we would be able to spread the labour around, with everyone earning a living by doing a paying job that doesn't occupy all their lives and energy.
But our economic models/structures are not (allowed to be) flexible enough to accommodate that so we've got what we've got.
