Did you factor the possible currency devaluation?
Indonesia gives you 11% per year for 24 years?
Dollar is a reserve currency, so there is very little currency fluctuation, and S&P500 index fund gives you a consistent 4% CAGR which is decent.
Indonesia’s GDP growth, averaged out over the last 24 years as over 11%. Once they did their reforms the growth was probably front loaded at a much higher percentage, probably the same case with India and China, all three over the last three decades.
There are probably areas within the economy that are probably even faster areas of economic growth, considering how backwards Pakistan’s agricultural sector is (with limited mechanized agriculture by world standards), better irrigation techniques, equipment, seeds, fertilizer and pesticides use, the growth in yields could be 3-4 fold what they currently are. Then you look at the potential to increase arable land into the four desert areas with an expanded canal network with the use of dams and water management, and you see this could be high growth. All of this taking into account the low labor costs, so you can pick and choose the best talent, to train and employ, at a competitive salary.
The rupees, once reserves go up, will strengthen. Economists would advise to keep it low to remain competitive, the way China did for decades, but the rupee will strengthen to a level in accordance with the stability and size of the economy. Heck, if the Pakistani GDP per capita reaches parity with the Indian GDP per capita, and the economy is equally robust and developed, the PKR will be back to 60-80% the value of the INR if not closer.
All this is to say, with even modest reforms and inviting investment to go big into Coal fired plants; increase coal’s percentage of electricity generation to 50% from the current 10% (remember India is about to invest $55 billion on new coal fired power plants this decade, this is on top of the fact currently 45% of their electricity comes from coal fired power plants) then the Pakistani economy will be stable and will grow out of the current problems.
The elite, who keep their money invested, will pay more in taxes but see many of their investments grow at least 10 fold in a couple decades, and it will be in an environment where they will be part of a class to set the cultural trends in the land they live, rather then living in a foreign country where their influence will be limited.
