qualifications are only worthwhile in narrow fields where the qualifications apply, they're worthless as measures in wider fields, i.e how the country should be run
intelligence tests don't even have narrow applications, they just show how well someone did in an arbitrary exam
For the general public I agree with you, but politicians should not only pass an intelligence test but also a general knowledge test, on top of that they should get tested on special fields when they are in the run for a minister. These feckers are the dumbest living being in every country.
