Pakistan dont need this democratic system and we need something different but definitely not dictatorship.
If you have 100 million then you will be able to launch a campaign in one constituency and there are 272 constituency in pakistan so multiply by 100000000*272 = Rs. 27200000000. and we have two major political parties so multiply by 2 * 27200000000 = Rs. 54400000000. and we have numerous small political parties then add more approx like half of each party amount that means 27200000000/2 = 13600000000 then 13600000000 with 54400000000 = Rs. 68000000000.
You know what 68000000000 means its 68 billion rupees and if we divide it with dollar rate which is approx 90 now that means 7600000000 $ and that seven hundred and sixty million dollars are spend on the corrupt political system and in the end what we have got matric pass, dacoits, land mafias, gangsters, foreign lobbists and capitalists. 
I am not including the senate election in the above. so calculate it too.
there are 100 senators and we assume that if half of the senate election seats are paid then one seat may requires around 100 million rupees then multiply by 100million with 50 which will be 5 billion rupees and add with the above.
Its a huge amount that spend for what? for destroying the organizations like PIA, STeel Mill, Railway and ……………
The amount can be spend for social development work but this will not stop yet because,
Now after winning all those election what will they do, first they recovered the expense amount and then start looting for the next election and then start looting again for the swiss account and then remaining will be spended in luxurious Mercedez, London flats, millions on jewelleries and you what will remain next??? answer is IMF and World Bank and UN Aid.
What a cracking system it is.
What a system that Western imperialist discovered.
