The market is in no way a democracy, by the way.
Why not?
==============================================
Jeez, you really believe your own wacko bullsh*t.
Here is why not, nonetheless:
The basic principle of democracy is one man, one vote. The market follows the principle of one dollar, one vote, and since money is distributed in a very non-egalitarian way, that is in no way related to one man, one vote. If I have one vote, Steve Forbes has ten thousand, and the average guy on the street has none at all.
There is absolutely no benefit to the average Yahoo user in Microsoft taking over Yahoo. There was absolutely no benefit to the users of BellSouth, Cingular and other companies for AT&T taking them over. About all you can say about Microsoft is that it is monopolistic and far too large already. AT&T's real motto is "the highest prices, always: the bigger we get, the more you pay and the crappier the service"
Still, it is the market that favors the gobbling up of the big and small alike by the huge and monopolistic to the disadvantage of the consumers and users.
