It happened several times in history. Governments are not divine, they are made up of human beings - and like human beings, therefore, are flawed and temporary in nature, and don't last forever. There was a time when our current governments - indeed, our entire social system - looked very differently.
Since you are sure it happened in history (not once but several times), I can't add anything.
By the way, most people believe that, in the near past, politics was better. The reason in having such impression is that, in everyone's past (when he was a kid), his parents likely used taking care of him and protected him, as possible, from all sorts of troubles. Only when he became an adult, he started perceiving the real world around him. Therefore, even now while the international Terror is launched against the ordinary people in almost all countries in the world (after being introduced with a great success, in daylight and as high as possible, on the tragic day, 9/11/2001) our kids (protected from this Terror and various sanctions) will see the real world later much worse than of today's.
Forgive me if I don't consider that such a startling revelation, but of course different people witness the same events differently; given differences in their own situation - both individual and collective - how else could they not?
I would argue that a major reason why history exists as an academic discipline at all, is to cope with that fact, and try to make sense of those multitudes of perspectives and interests in a way that can tell us anything meaningful at all about the past (and our present).
Being sincere, as you are, is the greatest priceless gift that someone can offer to another. (In fact, big amount of money and efforts are invested yearly to know what people have in mind
).
I have another major reason why history exists as an academic ‘mandatory’ discipline in every country.
Human history (religious or political), by the way it is presented in every region, proved, since always, being one of the best tools that divide peoples around the world (if not locally, among the ones living in the same region).
So I used being interested more in reading between the historical lines where some important truths may be deduced and the ordinary people are not supposed hearing them openly and clearly. Perhaps someday we will talk about these historical hidden truths (there are many) though obvious
For example, which side in the world, at the end of the 19th century, was supposed to be the worst enemy of the continent Europe?!
