Yes, and also I think there is a widespread misconception about the "distribution of income". How many do you think perceive it not as the statistical term that characterizes occurrence of numerical income values by quintiles but as some powerful group at the top actually taking the pie and slicing it according to their interests?
Distribution of Income and 'quintile' abuse is a favorite chestnut of mine.
In one of my favorite economic talks of all time, Dr. Laura D'Andrea Tyson, in Nov 1997 at UCal/Berk, spoke on CSpan about economic planning during the Clinton years.
Here In it, at one point, she admits, basically, 'Nothing we did.' She also discusses the relative ineffectiveness (by the numbers)of the 3.6% surcharge on incomes over $250,000/yr in explaining the surplus.
But one of the other highlights, for me, was the Q&A after the talk, when one of the local Berkloids laments the '8 or 9 to 1' ratio of upper quintile to lower quintile income in America. When I heard that, I nearly fell out of my seat.
Imagine the following thought experiment: assume incomes are purely uniformly 'distributed' from 0 to MAX_INCOME. That is, exactly the same number of folks earn 0 as earn $1/yr as earn $2/yr as earn....MAX_INCOME/yr. A totally flat 'distribution' of income. (How? Assume that 'income' is assigned by a perfectly random income generator, and is assigned to each of us as we leave HS.)
What will the ratio of the upper quintile to lower quintile be in this hypothetical world?
The average income of the lowest quintile will be 10% of MAX_INCOME, because the income of the lowest quintile ranges from 0 to 20%.
The average income of the upper quintile will be 90% of MAX_INCOME, because the income of the upper quintile ranges from 80 to 100%.
The 'quintile income' ratio would be exactly ... 9:1.
And so, my laughter at the Berkloid's lament. Apparently, there is inherent danger to something called "S"ociety when the ratio of a hypothetical non-entity called 'quintile income' is compared across hypothetical quintiles, and when this number reaches "about 8 or 9 to 1" our quintile income sensors(they are located in the middle ear, hidden behind the Incus--named for its ability to magically sense the ratio of quintile incomes-- literally, 'the income of us')start to flappergas.
And when we do the same exercise for decimiles, we get a ratio of 95/5 = 19:1!!!!!
And percentiles? Holy Percentile Crap! A whopping 99.5/.5 = 199:1! OH THE HUMANITY! OH, THE TYRANNY OF ... magnitude. As long as we 'allow' incomes to vary at all, even if we 'enforced' this totally blind/random distribution of incomes-- that, relative to a Bell curve had more share in the lower quintile by having more poor people than a Bell curve-- we are stuck with the consequences of ... simple magnitude. The only solution to this 'problem' of 'maldistribution' is to enforce INCOME=SAME FOR EVERYBODY...including my 18 yr old son with WS. Ie, the enforced abolition of quintiles...
Seriously.
I have been asking the same question for probably 30 years, and not a single redistribution warrior has ever been able to provide an answer: name even one thing that any human being in existence does primarily, secondarily, or 'at all' acting as a quintile. I will settle even for totally made up things, like, from a lost episode of Star Trek. Anything. Anything at all.
I beg of them....name just one thing that 'a quintile(with its income)' does in any of our economies---acting as a quintile. Please. After 30 years of asking, will one of these redistributuion warriors finally shut me up with an actual answer to this should be simple question, so that I can finally see the very first hint of the basis for their entire premise?
I looked at every one of my 1040s, and they all say INDIVIDUAL at the top. It took a while, because some of them were filed away. The word is not even even hidden. Big letters. Every one of them. Right at the top of the 1040. The IRS has lots of forms, and not one of them is filled out or directed at something called a 'quintile.'
Quintiles do not exist in our economies. They are mythical creatures of mathematical categorization that 'exist' only on the spreadsheets at Census.
I even try to help them with their argument, as in the following:
It is as if, once a year, we all show up to get into one of five freight trains, to have our freight train income counted(for some reason associated with abuse of politics.)
And then we get off the trains and go back to our lives. Next year, we don't all get back on the same trains, and by and large, over the course of our lives, we move from train to train.
Except for one glaring fact; we don't even get on the trains. The trains don't exist. We don't even do THAT as members of something called a 'quintile.'
And so, I'm not of much help to their cause.
Why does the quintile distribution of anything matter to anybody in the least? I mean, assuming that I was making up that whole Incus thing?
All it would take would be one example of a quintile acting as an economic entity.
Just one.
One.
30 years, and still waiting, but not holding my breath.
