> the perils of one group being able to dictate to others without input
This is pretty much the norm in any country that is a democracy but that does not have coalition governments. You get a kind of see-sawing effect where one group will enact a bunch of stuff and then when the tables are turned it all gets undone. It's stupendously inefficient.
Democracy is quite flawed but it still is the best mechanism for government that we have that is sustainable over a longer period of time.
