Is Democracy is too old to be suceeded by his son?

Is Democracy a success?How many can say a definite yes?or we can make it bear fruit by some 'eccentric modification'.
During a bus journey I thought about a modification,of course eccentric.
I compared our country to a Bus with Finance minister as conductor,Prime minister as Driver and cleaner as defense minister.
Prime minister is obviously the Driver.Finance minister is conductor because he collects revenue by tax and Defense minister wont allow unsolicited Intruders.

But in a Bus nothing leaks through conductor and all money reaches the owner.owner distributes the money.

That upper level is missing in our current system and we have only drivers and conductors and no one to ask where the collected money has gone.

I suggest some autocratic person above our elected representatives.

Or an Autocratic Group to make the representatives move in correct path when they are not doing so.

Group can consist of a Business leader(company which makes the maximum profit in that year),Retired Chief Justice,an Environmentalist etc.

This group should be able to control the representatives autocratically.

Democracy can be sustained by giving people the power to choose the representatives.

So When the Bus owner comes into picture,Can it produce result?...
