You are right. Deprivations of Balochistan people are not going to seize soon. I think the title of your post should be,' needed optimistic political approach' instead of the word 'pessimistic'.
I will little contradict to your arguments that Balochistan is 'purely being neglected on the basis of political reasons'. Other factors of equal magnitude are also playing detrimental role like you have yourself mentioned about feudalism, poor education of the masses, leadership vacuum etc.
Moreover, Balochistan is located at a point where the 'diverging interests' of the regional power converge. Wherever in the world, exist such locations, they are subjected to a number of severities. See what is happening in Afghanistan and relate its ill-fate to that of its geography. U will find the answer.
