products are identical and no one
will buy higher than market.
2. There is no reason to sell below market

Why "We're Different" is the
Adjacent advertisements in an 1885 newspaper for the makers of two competing ore concentrators (machines that separate out valuable ores from undesired minerals). The lower ad touts that their price is lower, and that their machine's quality and efficiency was demonstrated to be higher, both of which are general means of economic competition.
From chapter 22 on Understanding Profit
A. Price is higher than average total cost so total
is greater than total cost.
B. Cost includes a reasonable return on
investment called "normal profit" so under this

Purely Competitive Adjustment Causing
Serious competition from foreign manufacturers beginning with automobiles and steel increased supply causing Rust Belt Industries to lose their pricing power. This eliminated excess profits. Some industries incurred a loss as supply increased too much. Wage give backs began and many workers found themselves with stagnating wages. Companies used technology and outsourcing to be more competitive and maintain profit but this put pressure on wages.
This also happened in the finance industry with competition coming from foreign banking and cheap Internet trading. Their attempt to increase D for their services with exotic products like derivatives has not worked out well as of 07/01/10.
The bottom line is the standard of living enjoyed by U.S. citizens, their micro-lives, will grow more slowly as it is forced to share the wealth with people from around the world. We may even have to give some back because of our energy dependence and recent decadence though increased production of energy with shale has lessened lessen this dependency. But we will still enjoy the highest industrialized world standard of living in the.
Technology will continue to make our macro-lives

investments and collaborative competition in science helped by the Internet has
accelerate scientific advancement. Plus gains from science are often cumulative and while not
a straight line upward they eventually make our macro lives better. Think
childhood diseases being cured and smart phones. Plus its always good remember the best things in life will continue to be free and having enough
money is a function of demand, not supply. 08/12/11 updated 8/24/15

SWITZERLAND tops the latest competitiveness ranking from the World Economic
Forum, best known for its annual shindig in Davos (a Swiss ski resort). It is
closely followed by Singapore. Finland has topped Sweden to third place. Of the
big emerging economies, China remains on top, with Brazil moving up.
The most striking fall is the United States, which has dropped in the rankings for four years in a row. It is now seventh. The rankings are based on criteria such as institutions, infrastructure, financial systems, flexible labor markets, economic stability, innovations and public services. Plotting the scores against GDP per person reveals an unsurprising correlation: competitiveness brings wealth, but rich countries can most easily afford to provide the conditions for it. They can squander competitiveness too.
|Editors Note: Comparing the U.S. to anyone other than Germany and Japan is difficult as others are either small or developing. Plus we get a benefit from our being the world's currency which accrues from our being easily the world's strongest military and industrial nation. China assembles parts from all over Asia and has a way to go to be considered in this group.||
