It would be difficult to measure, but (as you point out) some newcomers might even struggle with the change MORE than those who are leaving.
The newbies seem to struggle with the fact that they are a part of the larger environment (be it the world or the neighborhood), whether they like it or not. Like the author, some take conscious steps to NOT express preferences and tell others about them.
However, faceless entities like "the business community" expect that they (as a group) will -in fact- express their preferences, as they have in every other neighborhood in which they have arrived.
Such generalizations offend and trouble this subset of newcomers; They want to think that they are different.
They want to be treated differently, because they believe they treat others differently.
As a result of inheriting the world in its present condition, they want to believe that the groups that they are a part of (perhaps their "generation") is different than those who came before them. That they are not repeating the "mistakes" of the past.
Slowly, over time, most come to terms with how much of life they can change. They reach an understanding of the power they possess, which includes what is possible in the present environment and what is not.
As a result of this process, some even forgive the prior generations for sins and "mistakes" they have perceived them of committing.
They slowly comes to terms with who they are, and to what degree others are like and unlike them. Slowly, they create a less rigid, less idealistic definition of what is "fair".
They realize that life is not as simplistic as what they may have been taught or concluded: It can not be simply defined and understood in terms of racism, classism, oppression and privilege.
At times it is painful to watch. At times it is humorous. Regardless, they have to go through it for themselves. Because if folks who have already been through it try to tell them not to go thru it, or to go about it in a different manner, or that they won't be successful,
....they (we?) will be told that they (we?) are jaded cynics, and sell outs who have become part of the machine that they believe is evil.
Our efforts may even make them respond by trying harder, which will just increase the pain.
Thus, our moral obligation may be to be quiet. Very quiet.
