The concept of the Overton Window is instructive here. Policies like "should local property taxes go up by .5 percentage points to fund school safety" are safely within the range of allowable discussions. These are issues on which the "elites" disagree, or don't have particular attachment to.

But questions that threaten their status, like "Is it good that individuals own the means of production?" are not going to be in the Overton Window any time soon, mainly because those elites agree that they like the status quo.
