There’s multiple ways to achieve the goals of a technocracy.
I agree with your criticism, but you’re criticizing a more extreme, centralized form of technocracy. I have criticisms of direct democracy, but I wouldn’t conclude all democratic systems are bad because of the most extreme version.
And democracy and technocracy aren’t mutually exclusive, either.
For the legal example, some states hold elections for their judges, and most require a law degree. This sets some minimum to be a judge in those areas, which is technocratic.
What if a judge claims other judges are fake? Well, the people can evaluate those claims and vote accordingly.
But at least you don’t have some unhinged individual with no understanding of the law abusing their judicial powers.
I can’t really speak to the bloodshed since I don’t know which electoral process you’re criticizing, but technocracies don’t need bloodshed, no.
For your goldbug criticism, here’s one potential example (out of many, many possible systems) that could resolve it: Academic and think tank organizations stake their reputation by nominating economists, and then the people vote on them.
Let’s say the Mises Institute nominates a goldbug economist. I highly doubt enough people would vote for them vs all the other candidates by organizations like the American Economic Association, etc. And if they do get elected, whatever chaos that ensues would harm not only the candidate’s reputation, but the Mises Institute’s reputation. People would vote them out and ignore candidates from the Mises Institute.
Yeah, I agree.
Poor decisions still happen, but this would be a nice safeguard to lessen the severity and frequency of such poor decisions.
Most economists today would not support a tariff and subsequently wreck the economy.
