Does Inequality Work? What seems to be at stake in the Big Question discussion is "how much equality of opportunity" exists. Achieving an equality of opportunity is far more difficult to achieve than an equality of wealth. A redistribution scheme could level up wealth very quickly. Engineering opportunity (if that is even possible) takes much more time, requires considerable intrusion into private life, and perhaps requires unique historical circumstances,
The various states, counties, cities, federal government. and NGOs in the United States have been trying to engineer opportunity for disadvantaged people since the 1950s. Supreme Court decisions, Congressionally funded large education outlays, laws requiring consideration of disadvantaged groups (equal employment opportunity programs), federally funded nutrition programs, mandated health care access, and so on have been carried out. Some of the programs have expired and been replaced in an effort to improve achievement of legislative intent.
Results are persistently inconsistent, inadequate, and uneven. Some groups, in some locations, have experienced an increase in opportunity -- sometimes substantial. White people (males and females, economically disadvantaged and not), gay people, persons with physical disabilities, various minority subsets have benefitted. Some people, including substantial percentages of whites, blacks, hispanics, asians, and American indians have scarcely benefitted at all. What's the difference?
Those benefitting the least from efforts to increase economic opportunity...
a. tend to have long, multigenerational histories of disadvantage which has produced deep poverty, social marginalization, and social exclusion.
b. tend to be located in regions where economic opportunity is in long-term general decline (like the Appalachian states -- Kentucky, West Virginia, Tennessee) and other areas.
Those benefitting the most from efforts to increase economic opportunity...
a. may be poor, but have multigenerational histories of literacy, striving, social mobility, social membership, and social inclusion.
b. tend to be located in regions where economic opportunity is upwardly inclined (at worst, level) and have a generally progressive culture.
So, poor white children on farms and in small towns (or even metropolises) in New York, Nebraska or California may experience inequality of economic opportunity, but they belong to intact cultures which inculcate economic success-related behaviors like literacy, perseverance, and planning. Though disadvantaged, they have many of the skills needed to benefit from "social uplift" programs like government scholarships for college. Some blacks, hispanics, and Asians share these characteristics and are able to benefit.
Poor white children in Appalachia, by contrast, are located in zones of multigenerational economic decay and collapse. They tend to be socially isolated, have lower rates of (effective) literacy, much poorer health, more insular cultural traditions. Many blacks share these characteristics: multigenerational poverty, social exclusion, insular cultural traditions, poorer health, lower rates of literacy, culture of poverty. So do American Indians. Hispanics may or may not, and Asians may or may not share these characteristics.
The people on the bottom (multigenerational poor, marginalized, insular, sick, etc.) are not in a position to respond and benefit from economic opportunity programs. They can't make it to the first rung of the ladder.
Those at the higher levels of economic success have opportunity "built in" and some of these prosperous people would have to go out of their way to fail.
So what it amounts to is this:
Those who have a lot to start with, keep it, and get more.
Those who can benefit do benefit.
Those who can't benefit lose what little they have and keep sinking.
Percentages?
20% = Most successful layer of population in US
40% = Can become successful if program exists and economy is healthy
40% = more or less permanently screwed
Upshot?
Those who are least advantaged economically will probably stay that way, barring a highly unlikely tremendous economic boom.
