That depends upon what "Equality of Outcomes" means. Does it mean everyone gets the same results, without regard to effort? The only practical way to guarantee Equality of Outcome is to require very little and give very little.
In an ideal world, all children should finish school with acceptable grades. Some will be above average and some will be below average. If "acceptable" is "equality of outcomes", then the mission has been met. It's fair to demand every child receive whatever assistance needed to achieve acceptable. Some may need more help than others. This means there will be inequality of assistance, just as there is inequality of effort.
This leads to another problem. Resources are finite. Do we give good students extra assistance, to help them become really good students, or should these resources be spent on those who are the poorest performers? Is there some kind of accounting where we can measure input and output, and thus calculate some factor of efficiency? This kind of thing happens in schools all across the US. It's called "Gifted and Talented" programs. I was born a little two early to be gifted and talented, but both my younger sisters were G&T. They don't actually have any great gifts or talents. What they had was my mother, who filled out the forms. It's never been a secret that one of the greatest inputs to a child's education is their parent's interest. Every gifted and talented child has an interested parent. It's very likely every very good student also has an interested parent.
If the resources spent on Gifted and Talented programs were aimed at under achieving students, it might be money well spent. It could also be money wasted, although the appearance of waste might just be a bookkeeping trick.
This is a case of the means must justify the ends. How does one achieve equality of outcome, when there is no equality of any other measurable quantity.
My first reaction to your post was to agree with it and then I realized the context in which agreement with your post would have to lie. So I ask you these questions and frankly they are difficult and I don't pretend to have the answers. The first
highlighted remark above represents a standard extractive view of humanity. There is assumed to be some sort of requirement placed on an individual to produce something society values. Take it from me, I hope you do, that
this is a moving target. It is as if everybody who describes a system feels because they are describing it, they must be viewing it from the position of the boss. Thus we assume that by sort of test we can ascertain some measure of each individual's productive capabilities. To the social planner, this test would measure "productive positive qualities" and the assumption is that the aid the system must deliver to the lower scorers is wasted.
So you tend then to permanently assign the definition to the receivers of aid as intrinsically defective. This amounts to a grand assumption that we can recognize valuable qualities in others in a quantitative sense and score them as human beings.
The problem comes up with the fact that society advances because people are always deviating from the norm in various ways and just like evolution or natural selection produces more likely to survive and less likely to survive, our culture, if it recognizes this concept, it must also recognize the absolute need for the variation and diversity even though some variations may be less quantitatively productive than others in a given work system. I think part of a truly humane or humanistic system of economics would devote a great deal of its efforts to match individuals with employment or work or whatever that would be suitable to them and still beneficial though perhaps only marginally so.
We in the western world seem to frown on frugality though frugality is almost always environmentally responsible. Some of us feel that life ought to be hard and work should be long and arduous and only slightly rewarded. Why we have this thought about work is that somehow in this extractive theory of governance, somebody is expecting to make a profit through their own brilliance. Our society has reached a degree of industrialization where many of the traditional work functions of human beings are being replaced by mechanical and electronic devices. We can argue about how well we mind our machinery, but the simple fact is that as we become more capable of machine delivered production, the need for men and women to slave at work actually should decline. We are not frugal with our substrate and habitually as a society destroy ecosystems that guarantee diversity. We do the same thing to portions of our population we have failed to come to satisfactory terms with. That is because we all imagine ourselves to be the boss. Just saying doesn't the philosophy tend to dictate not just that a person works to please the boss, but that his production must have a certain physical dimension and that dimension is great enough too allow a profit for the boss, otherwise, the low quality human beings can just go away. It is kind of like killing people without using a gun. We call that poverty.
The degree of disengagement of a system from the "lesser" members of society is directly proportional to the limitations on the understanding of the planners. Everybody should be active and employed or at least doing something that keeps them healthy and happy with their work. I feel our current system seems to produce unemployed who are expected to buy their retraining and sometimes their initial training with private funds they do not have. The student loan fiasco shows us how utterly divorced from the needs of the people of this country our institutions of higher learning are.
