Well, for once I agree with The Crow.
Does a male who earns £150k or more a year have a better or more weighty opinion than a female on minimum wage?
I fully understand the desire in a survey to put people into demographic categories, but I think it is unnecessary on a topic like this . . . . .
It should be noted however, that this is a "surveymonkey" problem and not one of the ATr's making.
