It's a shame, yes, but apparently that's what wins elections. What needs to change for that not to be the case? Is better education (better funding people's access to higher education?) the solution? Although it may have some impact if people are generally more knowledgeable, I don't think it'll be a solution.
I think it's a broad enough to be safe to say that what is required is a change in our culture - but what kind of change, and how can it come about?
