I figured it out today, why it seems such a mystery to modern cultures. (As well as any other wonder of the ancient world...)
Canada has a population of roughly 30 million. (~25 million 10 years ago) Unemployment rates have been on average about 5% over the last decade. So take 5% of 27.5 million people over 10 years and how many man hours do you get? A lot. What are we doing with them? Nothing.
That is a conservative estimate, as unemployment rates are usually double national figures in most countries. (The majority of unemployed people have no reason to report it to the government and nothing to gain if they did - like me.)
So take that figure up to 10%. That's 2.75 million people. Lets take a conservative work week of 40 hours for 50 weeks a year. That's 2000 man hours per person per year. 10 years makes that 20000 man hours per person.
20000*2750000=55000000000 That's 55 billion man hours!
(lets put a dollar figure on that - minimum wage @~$8/hr --> 440 billion dollars)
Now the population of the US is about ten times that of Canada - so that's 550 billion man hours of unused labour in the last decade in the US. (4.4 trillion dollars)
Then there's this saying... something about "idle hands"...
We could do a lot for our country with 55 billion man hours. We have an excess of food. (tons and tons are ploughed under every year) Plenty to fuel a 55 billion man hour engine. We have an excess of space and materials for shelter...
We could easily build a pyramid to rival the Great Pyramid with 55 billion man hours. Though perhaps a giant beaver dam would be more appropriate for Canada...
What set me off on this today, was discovering that there is actually an unemployment rate of about 4% in China. CHINA!
It doesn't need to be something worthy... as that is fraught with political implications should anything significant actually be achieved... which is why something like a pyramid is perfect.
These people want to work, they need to work, yet we give them nothing, that is why we are constantly amazed by the greatness of our ancestors and wonder what happened to the greatest timeless works of man.
It is time to revive the wisdom of ancient cultures.
