Is the public stupid? Maybe so?

Hello Rabbi,
 
In recent days, a phenomenon that began a long time ago has been growing, in which half the people think one way and half the people think another.
The small difference between the halves is who is in each half.
The revolution is supported by mainly educated publics (including Haredim, Mustard and Bibi supporters) and especially not by people who are (on average) particularly educated.
And the questions:
1. Is it people's common sense that if there is a large public that supports something, it is probably not the end of the country (because a public will not support its own destruction)?
2. Is it reasonable to expect from the media that every opinion supported by half the people will be represented in each panel in an equal percentage (half a panel)?
3. So, when there is a discussion about whether the revolution is harming the economy, is it right to bring in two economists who each think differently (some economist versus Sagi Barmak) so that it is half and half, or is it wrong to present it as an equal debate because 99 percent of economists think something?
4. How can an educated and serious person like Nadav Shnerb support this?
 
Thank you in advance.
