You're being disingenuous. 'Concentration of economic power' means a small group controlling a relatively large share of overall wealth, not "coordination of the activities" in an industry, aka cartelization.
First of all, RPA, 'concentration of economic power' says nothing about the DEGREE to which wealth is concentrated. My definition is accurate, yours is not. My definition: concentration of economic power: "the phenomena of the amassing of wealth and power." It says nothing about large and small groups, and please don't tell me I'm splitting hairs because this is an important distinction.
And second, AGAIN, you've failed to comprehend my argument, look at the VERY NEXT line:
"If you don't buy that, if you can't accept that the coordination of members of a cartel isn't in itself a concentration of economic power, then we can at least agree that the ability of companies to cartelize is a negative impact of the concentration of economic power, meaning it is an indication of the destructive potential of economic power, which is what I claimed Adam Smith recognized in the first place. In referring to this thing, cartelization, negatively, Adam Smith has recognized a destructive potential of economic power."
I personally, and this is my belief, view cartelization as a further concentration of economic power even though the dollar amount in these few individual's banking accounts may not have (immediately) risen. I believe this for two reasons: one, it has many of the same effects as concentrated economic power (streamlined decision-making, ability to price-hike, and the potential for coordination of activities outside of price setting), and two, it creates an inefficient industry where consumers are shorted so that company owners can see a greater share of profit. HOWEVER, if you don't buy this argument, it is STILL an obvious conclusion to arrive at that if we don't see cartelization itself as a concentration of economic power, we can at least see it as a
negative effect or an
example of the destructive potential of concentrated economic power, and Smith certainly saw it this way, which is why he was trying to dissuade the reader from believing cartels would develop.
Let me reiterate: Smith did not try to argue that cartelization was a positive development in the market, in fact, he attempted to persuade the reader that cartels rarely form:
"People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices."
This shows that Smith saw the destructive potential of cartels, which are, at least, a negative result of the further concentration of economic power, if you don't buy my argument. Come on man, when there are few firms in an industry, there is further potential for cartelization, only an idiot would deny the existence of economic power.
