See the current system makes it difficult to transfer power to other parties e.g PTI, and the system is run by PPP or N-league, so they'd never change it to benefit the true spirit of democracy, since they are pre-occupied by their personal agendas and power.
To me the most important thing to consider is that we, the educated class, make only 30 % of this country. We watch politicians speak on tv, we judge them, we see corruption cases, and then we decide on those merits that current government is a problem for the country, and their should be a change. But who will tell those 70% rural people who does not have internet or cable, its their vote in the end which makes government. These PPP and N-league politicans know the tactic, they know that even if they give away free food and some money those 70% will cast vote in their favour. So their's a dire need to teach people that every individual vote has a power, and that their vote is a national duty which they have to do in the best interest of the nation, not the best interest of individuals.
Secondly, unfortunately those of us who are educated and know the nation's true interests dont even bother to vote, if we all vote and encourage people to vote in national interest may be we can bring a change, it needs patience to bring change but its not worth waiting, its worth acting now. Thats my humble opinion.
