Well, these days Pakistan has coalition government of two mega-corrupts, Zardari and Shareef. Both have teams of corrupts with them and no one to control them. So, when we are talking about $30 billion expected investment then here is how it would go:
Zardari commission = $3 billion ($3 billion, or most would end up in Dubai or West) Shareef commission = $2.5 billion ($1.5 billion would end up in Dubai or West) PMLN lesser choors = $3.5 billion ($2 billion would end up in Dubai or West) [PMLN lesser choors are bigger choors than PPP lesser choors, as PPP lesser choors do not have that much leverage in party decisions as PMLN lesser choors] PPP lesser choors = $2 billion ($0.5 billion would end up in Dubai or West) Government servants who would take their cuts (it is them who corrupt politicians use to get commissions, so when corrupt politicians rule, government servants get good cuts too): combined $10 billion ($3 billion would end up in Dubai or West).
Total to corruption = $21 billion ... out of that, $10 billion would end up in Dubai or West. Total what Pakistan would get in investment = $9 billion ($30 billion - $21 billion)
Pakistan credit rating has gone down in recent months (and most likely it would go down further), so all these investment would come expensive, not at 4 to 5 percent interest what we were getting when Shaukat aziz was there, but most likely at 15 percent or more. That means $30 billion (actual = $9 billion) would cost Pakistan $4.5 billion a year (or more). Pakistan would keep borrowing to pay just interest (or guaranteed return) on that investment. Most of those borrowings would go in the pocket of corrupts too. That means, soon Pakistan would be in similar situation what it was during 90s when every day Pakistan was struggling to pay interest on dollar debts and was sitting on verge of bankruptcy. Since two mega-corrupts have joined forces to loot and plunder, it seems that Pakistani situation is getting towards situation of 90s quite rapidly.
Even though $30 billion investment might be enough to pay $4.5 billion to foreign investors (after a bit of stretching), obviously investment of $9 billion is not enough to generate $4.5 billion to pay foreign investors, so Pakistan would pay from own pocket, curtailing development budget and borrowing further. We can expect that, as Pakistan in 1999 was borrowing heavily to pay debts plus investing nothing on development because total tax collection was less than even defence expenditure plus interest. Pakistan was borrowing not only to cover defence expenditure and interest payment, but also for day to day government expenses. Fortunately, this government received an economy that is generating taxes not only to cover defence expenditure, interest payment and day to day government expenses, but Pakistan is left with 100s of billions from taxes for development expenditure and subsidies too. I feel that with fast increasing debt and corruptions, this condition of excess tax revenue may not last long.
I am hoping and praying that this does not happen but knowing past of the crooks in power, this might happen, and thus I have to pray that before these two thugs completely destroy the country again and bring it to similar position where they left Pakistan in 1999, something happens, that halts this deteriorating situation quickly.
Ignoring the name calling and galli galouch, the investments during Shortcut Aziz's times were either just promises, or numbers, nothing really happened, pehley bhi bijli nahee thi, aur ab bhi nahee hai, thanks to the unprecedented corruption in the last decade.
