What is fair about a political system that has given rise to an elite and an underclass?
What is fair about a 100m running race in which one person wins and another loses?
In both cases, a set of rules which apply equally to everybody who starts.
Elites and underclasses existed long before parliaments, so you can't really say that anything in our current forms of government gave rise to them. At best, you might say that our form of government perpetuates them, but then so does every other form yet devised, many more so than representative democracy.
Imposed government from afar is colonial rule.
That may be true, but it's irrelevant to this discussion. Scotland is part of the same small island as England and, for all the faults of our mutual history, acceded to the union voluntarily, so the rule of Scotland from Westminster is neither 'imposed' nor 'from afar' in any common meaning of those terms.
