You are trying to sound like a real economist and I can see your fellows clapping and stamping their feet for you. Well, you are just a wannabe. A fellow who the word economics is as foreign to as the profession itself. In my entire life, I have never seen a case where having a stronger currency is a disadvantage and having a weaker currency is a blessing in disguise. If that were the case, Zimbabwe would be a flourishing African state used as a case study as far as development is concerned. Everything you are saying here is just hot water, empty rhetoric meant to hoodwink your fellows and massage their egos.
Saying that $500 million can do more in Tanzania than Kenya because Kenya has a stronger currency is baseless argument that lacks an iota of truth in it. That money can only do more in Tanzania if the cost of raw materials and other factors of production are cheaper in Tanzania than Kenya, but not because Tanzania has a weaker currency. That is stupid argument and way of looking at things. How does a stronger currency result to high cost of production as you imply above? What economic explanation can support this argument? High costs of production come as a result of many factors, key among them being taxation, cost of electricity among many other things. I have never seen a case where having a strong currency is a factor leading to high cost of production.
