Further down in the article, it says: "Of course, people tend to show more moral gumption in surveys than they do in real life. In part this is because we are dealing with hypotheticals (who isn’t against child labor, in principle?). But also, people don't usually ponder issues of inequality while they’re buying their milk and groceries."
"[A]s of 2010, only 34% of people polled strongly supported letting homosexuals serve in the military, but half again as many — a full 51% — expressed that level of support for letting ‘gays and lesbians’ serve in the military. Ever since reading that I’ve worried about how many important decisions are being made by the 17% of people who support gays and lesbians but not homosexuals."

I think certain words are given negative/positive associations by the media and those overtones have a lot more impact if you're only spending 4 seconds per question than if you're really thinking about it.
Those are not the same thing, though. Someone with a low income has a job, presumably.
Tons of people. They need their children's income.
