I guess I must be "severely intellectually challenged" then!
The good news is that you are in good company,
Most people are "reasonable" in their own ways. So most people would want a "reasonable" wages for everyone, even though "reasonable" wages may mean differently for different people.
The survey explored that fuzziness. Rather than presenting a specific number or a range of numbers (so to eliminate such subjectivity), they asked if the subject supported "reasonable" wage - obviously most of them said "yes".
The lady then translated that support for "reasonable" but undefined wage as a basis to justify her specific demand for minimum wage, to imply that 90%+ of the people surveyed supported her specific minimum wage. When in fact, those people only supported an undefined "reasonable" wage because that was the question asked of them.
It doesn't take a rocket scientist to spot such dishonest propagandists - I think they teach that in elementary schools. But it is unfortunate that people like the lady prey on the less-than-informed.
