I think you're misquoting me. Kenya will become developed in 2050 - not in 50yrs - but in 30yrs. Kenya will join the proper middle class (like South Africa) in around 2032 when Ruto finishes his 2nd term (GDP will be around 300-400B dollars against a population of around 60M then).
WB/IMF define the terms here
Threshold GNI/Capita (current US$)
Low-income < 995
Lower-middle income 996 - 3,895 - Kenya is here now - GDP per capita around 2,000 now.
Upper-middle income 3,896 - 12,055
High-income > 12,055
My projection is that Kenya GDP will be around 150B - in 2023 against pop of 52M - around a GDP per capita slightly shy of 3,000.
Kenya will join upper middle class when it get to GDP of possibly 200-250B dollars & pop of 57m -by 2027 (3,900 usd threshold) - and definitely by 2030 it's GDP per capita will be around 5,000 -(GDP greater than 300M for pop of 60M).
By 2040 - Kenya GDP will be around 1 trillion dollars then with a population of 65-70m - Kenya gdp per capita will be around 10-12k - at the cusp of a developed country.
By 2050 - Kenya GDP may well be around 1.5 trillion dollars with a population of 75-80m - comfortably a developed high-income country.
The reason why this will happen - increasing economic growth rate and rapidly declining population growth - meaning more wealth is being created.
About economic development, I might be wrong about Ruto - but you're wrong to state "Kenya we are on the cusp of a revolution" or "we are on the verge of prosperity". No we are not. You acknowledged in the past that it will take 50-100 years to rise to developed market status. The "cusp" or leapfrog and 50-100 years long wait can't be true at the same time.
