Any individual is only capable of considering a HANDFULL of alternatives at a time, right?
So it would need a huge amount of individuals in order to consider all the millions of alterantives necessary to, for example, produce a pencil.
If each of these individuals are free to choose, they will generate prices. So instead of having to consider all millions of factors which produced the pencil, the consumer only needs to consider one single factor, namely the price of the pencil! That makes it so much easier to choose between buying only one pencil and a chewing gum, or rather two of the same, doesn’t it? Prices enable decision making.
Prices stems from, and have their value in, human beings having a limited scope of attention. To price something is like passing the ball from one player in the team to another one who is more likely to score (and getting credit for it in return).
Communism is the idea that the Leader can span millions of decisions simultaneously. It is the religion of the almighty God who magically will make everything good by force of his super humanity, which in lack of real results often is manifested in huge statues…
Social democracy is the idea of everybody simply sitting down and talking about everything. Equally. Todays issue is pencil-making. Does any of you millions gathered here today know about the location of any suitable graphite mines? … And meeting suspended. Tomorrows meeting will go more deeply into the issue of graphite mining in Tasmania and the question whether women should be forced to work those (potential) mines, as well as the raised issue of 7 weeks hollidays for those who will work those same (potential) mines, except for workers of age less than 27 years (as defined by the age of the date of August 16th) who should only have 6 weeks vacation, and locals who should have 8 weeks vacation and so on and so on and so on and so on and so on and so on and so on and so on and so on and so on and so on when EVERYONE must have their say about EVERYTHING.
And then there are billions of other objects other then pencils to have endless democratic meetings with everyone about, aren’t there???
But how could democracy fail when EVERYONE comes together at the same time? Because ALL knowledge resides among everyone, that, I think, even Mises agrees upon. But even gathering ALL KNOWLEDGE on the same spot at the same time and “talking it all through” democratically, doesn’t work. Only capitalism works…
