First, last and all the way through, there are no absolutes in government. Everything changes and attempting to find and define prime causes in order to design a master plan that will cure all ills for ever is doomed before it begins. Some wiseacre once said (or if he didn't he should have!) that government is 'the art of the possible'. That is why all 'master plans' are doomed to eventual failure whether they be Marxist or Fascist. We are lucky in this country that being an Island which has resisted foreign invasion since 1066, we have slowly, gradually, inch by inch developed a system of government that, despite its frequent errors and calamities, has self-corrected itself and thus kept itself on course for a system that is about as close to realistic democracy as you can get, and certainly much closer than all the man-made and manufactured systems that sundry intellectuals have sought to impose on their peoples.
It ain't perfect! But nothing is. Therefore it is always critical that the system can be corrected by those who are most effected by it. The recent EU referendum is the perfect example. Millions of people in Britain felt both the pressures and enjoyed the advantages of being in the EU because, of course, like every other system it was not perfect for everyone. Because of our history and the system of government that it developed, we, the British, were given a chance to make our judgment. We voted to leave. That may or may not prove to be right in the short, medium or long term but the absolutely crucial factor is that after 40+ years we were allowed to choose. That act of choosing is the single greatest political virtue of which we, the British, should be immensely proud.
As to the future, no-one knows but at least we can be comforted by the fact that our working - not theoretical - democracy is in good order.
