Suicide, drug use, and alcoholism have deeper cultural ties. I have no idea what those ties are, but it likely won't be fixed by a 4% annual increase in wages.
I can't help but wonder if perhaps this increase in self destructive behavior is due to an increase in secularism. Blacks and Hispanics are more religious than whites, and with that religiosity comes greater church attendance which likely brings greater community support (a generalization, I know, but I'm guessing that this is probably more true than not).
One possibility is that we're seeing a confluence of trends: continued improvements in minority life expectency due to better service and access, but still making up for past deficiencies. While whites are being hit by the leading edge of both decreased access and falling economic opportunity.

to the US in general:

The military has a slightly higher percentage of whites than the general population (and much higher percentage of males). Not quite the right age group, but I wonder how military service factors in.
You have to be standing up to be knocked down.
I found an article about this:

So at least one study seems to support the hypothesis (interesting that it also showed increased substance abuse, which was also discussed as one of the culprit's of the higher death rate for white men).
Maybe there are a tiny number, but I've never heard of such a thing. Re-educating fifty-year-olds into complete new fields on any mass scale is just not realistic. We're talking about millions of people that have minimal math skills, mediocre writing skills, and no computer skills. Even if we figure out a way to make older brains learn so much new information, it would take years just to catch them up to a college-ready HS diploma.
This should surprise no one. These are the people who work marginal jobs and they have been the most affected by so much manufacturing moving offshore, the resultant shift to service sector employment, and the downward push on service wages created by massive immigration of unskilled South American workers. (Not to mention the political and social demonization of this cohort.)
