There is a sticky thread here called "The system" or something along those lines...there's some interesting and sometimes rather philosophical discussion on what's wrong with the system in Pakistan or how it can be improved...I talked about this very problem on there.
Pakistan's democracy isn't really democracy. ppl's rights aren't protected(especially if u r poor), ppl aren't represented properly, etc...it pretty much fails all the tests to prove that it is democracy.
Instead it's just a sham...when humans collectively moved away from monarchy(which used to be widespread and is close to non existent now), they thought we should limit power and for good reason(the ideas of John Locke and others during the enlightenment)...and so power was distributed and checks and balances introduced etc...
so power was taken from the 1 monarch and distributed to let's say a 1000 ppl...but it was only a matter of time before these 1000 ppl realized that they can just work together for their own benefit(kind of like u scratch my back and I'll scratch urs)...and so we r essentially back to square one. This "democracy" really has just a few select group of elites that are all in it for their own benefit...they use/abuse the power/money to their own advantage just like how a monarch could...they can oppress the common folks just like how a monarch could...or alternatively they can do well for the country too just like how a kind/just/honorable monarch would...but the chances of that ever happening are far too little.
