At least in politics, I'd argue that it is not shamelessness. It is a reaction to the fact that our political nobility have sunk so low in terms of achievement and results, that they made a mockery of democracy.

As a reaction, the public makes a mockery of them. As a bonus, getting a politicians that speaks his mind in the common way, is an added spice! Seeing the revulsion in the faces of the political nobility when Trump opens his mouth, gives many satisfaction.

So in politics, this is a sign of health. It is a kind of catharsis. Trump was one of the first in the modern era, and he'll get copy cats, and the strategy will then start to lose its efficiency, but, it will have recalibrated politics away from the previous state where it was a toy for the nobility and commoners were not welcome.

This is also something they fear. That commoners, not part of the nobility, might gain entrance to their domain.

So this is a healthy sign for democracy!
