Is the democracy a pantomine?

It seems that eventually Egypt and its neighboring countries have chosen to rebel against the totalitarian system which prevailed in his country. System that only benefited a few people. Where the rich were very rich and the poor very poor people.

Now many of these countries opt for democracy. It seems that this step will benefit those countries where the majority of the population lived in poverty. But the democratic system is the best? or is it the best we have found so far. Because we have also noticed lately that there are perversions of democracy, such as Italy. Where nowadays the population is facing and fighting against the Silvio Berluscioni power abuse.  

Therefore, the democratic system, which seemed the best system is suffering the consequences of the greed of man. One example is Spain where corruption is very present there recently. Although it appears that attempts are being made to eliminate these types of corrupt behavior. The population knows that this is only a pantomime. The only chose some victims to cover up the reality.

And if this happens in Spain, also means that it could be happening in to other countries? Is the democracy end? or it will remain, since some people is interested in it and because also the word democracy sounds good in the public eye.

At the moment it seems that the democratic system is what works best and prevailing worldwide, but you've ever wondered if one day be obsolete?
