FW: [GBlist] re. Piece of the "pie" and other guilt trips
Title: RE: [GBlist] re. Piece of the "pie" and other guilt trips
Sorry
to continue this thread , I know it's off
topic -- but a few additions
mule
driven grinding wheels allow individuals to be more productive than grinding
grain by hand. (including the extra cost of building the mill, and everything
involved in keeping and caring for the mule)
the
10th century invention of cams, combined with water powered mills, greatly added
to the productive ability
same
too the with the rise of windmills and tide-powered mills.
the
printing press made increased the production of text by over 100x (barbara
eisenstein) compared to handwritten manuscripts. Not to mention the increased
accuracy and the ease in diseneminating charts of figures and illustrations. As
our techniques have improved one person can now produce 100x more printed
material than 16th C printers.
One
person in the NYTs printing room can produce 1000x more words / day than can a
scribe. Imagine handwritting or typing the NYTs. How long would it
take?
Are
there other factors involved? Yes of course. Would we be better off if we
placed newspapers in public squares so many people could read the same copy?
etc...
The
purpose of this post is to address the issue of productivity. I state it
again. Because of technological advances one person can easily be 1000s times
more productive than another.
Again
-- this does not mean that the person is better, or that the productive effort
would not be better spent
elsewhere. It is a comparision of productive output v productive
output.
-- How
many newspapers (words) were printed per person?
(The
question of whether we should have printed them is a different, although
related, question.)
-- How
many tons of X (steel, sheetrock, bricks) were transported from place A to
place B.
(Again
the issue is not whether the building should or should not have been built, or
have been built differently; that is an important, valid issue but not one that
directly relates to the productive ability of the people transporting X.) I
would argue that with all the ancillary efforts required to keep the machinery
intact that, as with the upkeep of the mule in the first example, net
productivity has improved many fold.
