The implication being:
If you write a long book with reams of data, it must be right.
Some people need to attend a logic class. Universal truths are easily encapsulated in a paragraph or less.
Genovese was a first rate economic historian who wrote with a style that thoroughly laid out the evidence for his arguments; he was famous for it. My mention of him was an inside joke about Piketty's style which seems to be much the same. I think Kimura has at least heard of Genovese's style and would appreciate the reference.
Now if you want to talk about someone who did the same thing and took to the extreme of being unintelligible, you would have to read Joseph Schumpeter. In his "History of Economic Thought", he got to about page 3000 when he had the bad form to die. It took his widow 17 years to finish the book, and she had to skip a lot of topics he had outlined but for which his unfinished notes were inadequate to base a meaningful chapter on.
Theories that form the foundation for higher taxes on wealthy would be met with less skepticism if the recipients who promote such ideas didn't stand to be on the receiving end of their professed munificence.
This is an age old behavior of the statist, religion employed the very same tactics. Give us your money and we promise you a better future. Behind this exhortation is the use of language designed to be impervious to the layman. "Why should I give you my money?" says the "slow witted" farmer. The economist says "You don't understand our language, G = \frac{1}{n}\left ( n+1 - 2 \left ( \frac{\sum\limits_{i=1}^n \; (n+1-i)y_i}{\sum\limits_{i=1}^n y_i} \right ) \right ) ". Religious authorities took it a step further, they prohibited translation of the Bible into Latin upon punishment by death.
Giving anyone the power to redistribute money is a proven recipe for corruption.
Mencken, the brilliant American journalist, stated it well in his chapter the Social Contract from Prejudices:
"“All government, in its essence, is a conspiracy against the superior man: its one permanent object is to oppress him and cripple him. If it be aristocratic in organization, then it seeks to protect the man who is superior only in law against the man who is superior in fact; if it be democratic, then it seeks to protect the man who is inferior in every way against both. One of its primary functions is to regiment men by force, to make them as much alike as possible and as dependent upon one another as possible, to search out and combat originality among them. All it can see in an original idea is potential change, and hence an invasion of its prerogatives. The most dangerous man to any government is the man who is able to think things out for himself, without regard to the prevailing superstitions and taboos. Almost inevitably he comes to the conclusion that the government he lives under is dishonest, insane and intolerable, and so, if he is romantic, he tries to change it. And even if he is not romantic personally he is very apt to spread discontent among those who are.”
