Kagame and Lee Kuan Yew
On one level, Kagame is "cleaning up" Rwanda like Lee Kuan Yew did with Singapore. Low key, that's EXACTLY why Kigali and Rwanda as a whole is so clean. That zero tolerance steez. (it's why Singapore is so appealing to dictators/big men/strong men. )
But...
History is a Beach
Singapore's history and geographic location are very specific. Part of the reason HK and Singapore were popping was English colonialism.
HK used to handle a lot of what Singapore does now, but PR China messed it up for HK. So a lot of the banking moved to Singapore.
The old HK wasn't all banking either, but the people in charge of HK - land owners and bankers - decided to ride with HSBC n'nem and get rid of their manufacturing, creating a very stark bimodal economy.
Who's to say some other geo-political move won't disrupt Singapore?
Industrialization
Korea, on the other hand, said hell naw to IMF/WB and industrialized. Like China and Japan, they're paying for it now - working culture killed their birth rate - but the pay off for their society was staggering economically.
Kagame could learn to avoid the work/life trap and still industrialize.
Better to be the Germany of Africa than the Singapore of Africa, imo.
Development Politics and Lending.
The way geopolitics of development work now - they want the 3rd world to make software or other high value add services, so-called leap frogging. Meanwhile the G7/G20 got to where they are now by learning how to make physical stuff. That making of physical stuff meant lots of workers.
If it's just computer programmers, data scientists, marketers + street food vendors, drivers, porters, maids and farmers - that's not a good mix.
A society needs and should want a broad middle class, not the uber rich, some what rich professionals, and an ocean of the destitute.
