They actually do, if you ask them better questions. "Inequality" is a boogeyman that has a lot of baggage attached to it by society but, if you were to ask people if it was a good thing for millions of people to be lifted out of poverty if the cost was that on person was obscenely wealthy, most people would side on the side of inequality.

"Inequality" is just an academic word for "Keeping up with the Jones'". Each generation has more material good, both necessities and otherwise, than previous generations. It's only through comparison that people are made to feel poor. Rather than look at trends of poverty and flourishing, people are made to feel cheated by not getting a slice of someone else's pie.
