So let me see: the Wall Street Journal set a quiz, found that liberals didn't agree with what the WSJ thought were the right answers, and concluded that this proves liberals are ignorant of economics.
Oddly enough, liberals would probably give "unenlightened" answers to a quiz they set on politics, too. What an ignorant lot we are to disagree with the WSJ!
Now, I'm only an amateur, but I'm pretty sure several of those answers are hotly disputed by economists. But of course the WSJ knows which ones are right. As for Q5, well, of course there can only be one factually right answer to "is this person exploited"!
As Tantric says, cute trick. It certainly worked on you.
