I'm with you there, at least in theory. Where this becomes problematic is when the electorate is continually duped into buying into the latest set of campaign promises - no matter how outlandish. You would think that the same crowd that bought into and were subsequently disillusioned by Obama's litany of unfulfilled hope & change promises would be more leery of the next guy who comes along promising free education, free medical and all the other Bernie Sanders socialist utopia nonsense. Nope. The lemmings don't learn.Since our government was designed and built as a service agency - deliver the mail, guard the coasts, regulate how many rat turds are allowed in my burrito - I'm not distressed that a lot of the public doesn't know or care how it works, any more than they do how their UPS gets delivered or Whoppers get made.
Same principle applies to Trump.
If the governed had the slightest inkling that what they're being promised has no chance in hell of ever being implemented, they'd be a lot less likely to buy into these unproductive populist movements. Bottom line - an uninformed electorate is just easier to lie to.
