¯\_(ツ)_/¯
Providing free buses to people who live far away from desired schools do not rub the act in the face of people who live near those schools and do not need buses. It might cause a negative side effect that school buses becomes a symbolic proxy for being poor, making those intended to use them less likely to agree to use them, but it extends the option available for those who only have few options to begin with. In contrast, free grade points is much more displayed directly in the face of other fellow students, both to those who get into the program and those who were rejected with similar grades.
Free buses does not provide any ambiguous borders or rules once the student is at school. The requirements and expectations of the student is same as any other student. There are few situation where uncertainty and doubt can occur between buss and non-buss student, except maybe for times of heavy snow or road congestion. To my knowledge, when students who depend on buses can't reach the school and thus given a pass to skip school, the other students are given the same pass. If we go back to the Swedish example, requirements and expectations get ambiguous when people get in through other means than merit, causing tensions between those who got in through grades and those who got in through the free points system.
Both systems has generalizations, so I would say that a way to improve the desegregation efforts would have been to skip the qualification of race and simply provide the busing to any individual that is below a set amount of wealth and live a distance far away from the desired school in order to need a bus. Such change might have saved it from being abandoned in 1988.
It's such a shame, because we want as a society the hiring manager to go to the reservation job fair looking for applicants. But the manager knows that there are precious few 'qualified' applicants and we recognize they will tend to maximize the efficiency of their time.
Of course, it isn't an accident there are few qualified applicants in those places. Poverty has a holistic effect on a group. My hope is that groups can somehow separate financial poverty from poverty of ambition to try to break these cycles and make progress. Every 'group culture' has a unique ethos, many poor groups had rich ambition and rose out of their poverty over time. To me this is the only way I can see real progress being made without giving up on meritocracy (and by extension technological/scientific progression).
So the question becomes - what does it look like to cultivate group ambition?
1. Generational support: believe your situation is not guaranteed for your children. Fight for them. Sacrifice for them.
2. Education/medical: we pour resources into certain underprivileged places (not groups, physical locations). This isn't going against meritocracy, it's a long-term investment.
3. Recognize that human civilization is at its finest when people believe they can rise above their circumstances, despite all the external and internal factors pulling them down.
How do you apply this to a system that has favoured certain groups for so long that the whole structure has close to none of those it supposedly wants to help?
You need representation from groups that need help in order to help. You need representative individuals in the organisation to guide it. You may have to positively discriminate at first, or else you won’t have any representative to draw from.
There are abundant examples of butchered attempts at ‘helping’ when those with good intent have no idea (this thread gives plenty of cringe inducing examples).
The key, I think, it making it clear what the role is and what is wanted to those that are there in that role.
Like violence, the solution to systemic bias are simple but unattractive. Don't display and rub symbols in people faces. Do not create ambiguous borders between groups of people. Treat each person as individual and avoid generalizations. Add social and economical support based on lack of those resources on an individual level, from the bottom up.
The progress towards equally would look very different if people weren't constantly doing the opposite in the belief that this time the symbols will convince the enemy of the wrong doing, the ambiguous borders will work, the generalizations will send the important message, and that top to bottom approach will create a foundation for change.
