Im reflecting from the pov of a parents role re: the kids. If you give the kids what they want, its going to be soda and candy every day of their lives. Some deciaions are tough, e.g. delayed gratification, and holding ones ground, but do voters even care about stuff like that?
Can we even hope on common sense, when the population is concerned?
The answer to both questions in your compound question is yes.
Now, good luck defining each of those.
Well who is any one individual - or even a small group of outside individuals - to decide what’s “best” for the country? That’s why we have “for the people”.
