Um... You realize that's the same thing I did, just with 10% increments, right?
We're also really only looking at a choice between 1 and 2, since 3 can't possibly occur in the scenario you've outlined. If we've broken the population up by income, and divided them into 10% blocks, then there's no way for average income and total income not to rise at relative rates. It's kinda mathematically required.
Nice to know that your shortcomings include math.
No. You're just arbitrarily doing something that makes no sense. I was very clear. I'm talking about percentiles
of the population. Not of the earnings themselves. That's a "strange" way to do the calculations, btw. What do you think you're measuring there?

Let's take the extremely simplified example of a society with 20 people making the following amounts per year:
$15,000,000
$6,000
$7,000
$2,000,000
$14,000
$19,000
$0
$8,000
$158,000
$0
$92,000
$31,000
$17,000
$54,000
$395,000
$1,040,000
$22,000
$33,000
$1,000
$680,000
The brackets I mentioned would go every $1,500,000 (that being 10% of the difference between the lowest and highest figures), so we have:
10th: $15,000,000
9th through 3rd: $0
2nd: $2,000,000
1st: $2,577,000
Wrong. We're talking about population distribution and how much they earn. As I pointed out earlier, the reason you do it this way is because we want to know how income is distributed across the population, not just relative to other incomes. By doing it my way, we have a clue how much more you can earn by moving "upward" within the economic spectrum
Since there are 20 people in this list, every 2 of them represent 10% of the population, so we just add them up this way:
1st: 0 + 0 = $0
2nd: 1,000 + 6,000 = $7,000
3nd: 7,000 + 8,000 = $15,000
4th: 14,000 + 17,000 = $31,000
5th: 19,000 + 22,000 = $41,000
6th: 31,000 + 33,000 = $64,000
7th: 54,000 + 92,000 = $146,000
8th: 158,000 + 395,000 = $553,000
9th: 680,000 + 1,040,000 = $1,720,000
10th: 2,000,000 + 15,000,000 = 17,000,000
That's how you divide a population into percentiles. And that's what I'm talking about. What this means, is that by moving from the 30th percentile to the 60th, you more than quadruple your earnings. By moving from the 10th to any other range is a massive increase (starting from 0 afterall). A modest increase from the 10th percentile just to the 20th, more than doubles your earnings.
That's what I was talking about. We're all taught that a "steep" progression of income is bad, but it's actually good because it means that a modest shift within the population results in a significant increase in economic result.
Contrast that to a shallower range and you'll see that the benefits of shifting position aren't as good. Let me reiterate that it's just as "hard" to shift X percentiles upwards within any economy regardless off the economic system you are in. The same rules apply to everyone, so looking at percentiles of population rather than resulting earnings provides us useful data, while you're measurement does nothing except make it appear as though having a higher top end is "bad".
I'm still not sure why you think that makes sense.

Huh. Aside from that one person at the top end, we seem to have a situation where the poorest block has more collective money than any other block, and so on. Exactly what my case 3 was.
Nope. You're just doing really silly math. What does your method of presenting the data tell us?
Quote:
Now, once again, assuming that it's split not into "10% of the population in each block", but "the range for each block is 10% of the highest income present", care to revise your answer?
Except that was the assumption I was operating under dork. How about you explain why you'd calculate the way you want to? It makes no sense. All it does is show up the income discrepancy between groups of people. Which I suppose is great, but the question I'm asking is whether that's actually a problem. Why does it matter if the top person makes 100,000 times more than the bottom person? Isn't it more important to ask how hard it is for me to make a living for myself? Why should I care how much more someone else makes?
