I will point out, that being against gay marriage may be “an utterly ignorant bigoted sentiment” but “utterly ignorant, bigoted” people have votes worth just as much as yours or mine.
Also, you reference expanding college education as a path to help for the people in the main article. What you miss is that they had good lives without college, or their parents did. College is supposed to sort smart from dumb people- but dumb people still vote and live. If you can’t handle college, expanding college doesn’t help. And if college changes so everyone can handle it, it loses it’s power of showing who is smart and who’s not. There are lots of people who don’t finish college, or are past college age so expanding college access doesn’t help them.
