Did you consider that perhaps having students from less wealthy and educated families enroll would cause "declining results"? The best way to ensure perfect scores is to exclude underperforming kids from families where parents didn't go to university and/or have to choose between soap and bread at the supermarket instead of educating their child.

I'm still genuinely amused every time I see a Westerner living in a democratic country claim their government is dysfunctional, lying, stealing and bad. First, compared to what country? Second, can't you elect a different government? If enough people agree with you they would vote for it, and if not enough agree then perhaps you are in a minority. If unlike many people on this planet you have a mechanism for peaceful replacement of power it seems strange to call for a revolution.
