Even if Rwanda's GDP doesn't grow to the levels of its neighbours, the good governance means the quality of life (& per capita income will rapidly improve vs its neighbours.
As an investor that is important. I am a small investor not a Warren Buffett who needs deals worth many Billions of $$$ to invest. I don't even have KShs 1bn!(Though I did way more than 1bn Zim$)
So what difference does it make to me if the GDP will remain 'small'?
BTW, look at Singapore vs Malaysia!
Greedy when others are fearful. Very fearful when others are greedy - to paraphrase Warren Buffett
