Expertise or the election of elected representatives
The right to stand for election means that anyone of a certain age who is a German citizen and who has not been deprived of the right to vote due to political offenses may vote.
This minimum standard does not exclude retards, psychopaths and sociopaths, fanatics and zealots, as long as they have not committed a “political” offense. And the controls on delinquency are extremely lax. And this is precisely where the problem lies: with such a virtually non-existent standard, precisely those unsuitable people are attracted to politics who should never have become politicians in the first place.
A democracy can only function if it pushes the best people to make a contribution to society. And on the one hand, the best must be selected, so there must be an assessment standard that checks the prospective politicians for suitability and, on the other hand, the best must have a positive interest in serving society and their fellow human beings.
The standards to be applied could be determined by suitable scientific institutes on the one hand in feedback with a referendum on the other, so that the basis for filtering the suitable and the willing is laid democratically / professionally / scientifically.
The same should apply here: The higher the offices, the higher the standards that must be met. It is not enough to meet the minimum standards and then to have been a narcissist’s porter for 20 years in order to qualify for a high state office.
Whether there are still willing people who meet the standards and at the same time are prepared to work for a symbolic salary (current salaries of parliamentarians can be regarded as symbolic) is a question of social esteem.
People who have built up a reputation through outstanding political work will certainly be able to monetize this reputation after their political career. And whether this would be the only motivating factor remains to be seen.
If, as expected, no suitable candidates for political office can be found, either due to a lack of qualifications or a lack of pecuniary motivation, the result without representatives could not be worse than in the modern Berlin Republic, in which blind actionism does more harm to society than inaction ever could.
