Actually I consider this a good development. Accelerating the diminishment of the dominant White voting class in the US.
Wow. I hope I'm misunderstanding what you're saying because this seems harsh and kind of elitist. The article cites education, income, drug overdose and poor health as the main factors for the rise. It didn't say the deaths were because these were bad people who didn't deserve to walk the earth. In fact the article seems to point out these factors affect many demographics, its just happened to end in death at a much higher rate for whites with less resources and education to cope.
I dunno about elitist, since I happen to belong to that "dominant White voting class" myself. And although our demographics are declining, our voter turnouts are still higher than most other groups nationally and in State-wide elections. Meaning we still have clout on election day, and influence with politicians.
Aided now, of course, by successful Republican Party efforts to restrict voting access by minority groups, and others that Republican strategists believe are more likely to vote for Democrats. It is that elitist membership that I repudiate for myself. Except, of course, to exploit it while it lasts to vote exactly opposite the way Republicans want me to vote, on behalf of the newly disenfranchised.
