First step is for people to have less kids. That will reduce their expenditures. For men and women to delay marriage until they are 30yrs.
Gov should go out there and encourage people to marry very late. That alone will save a lot of money because babies are expensive.
With 500shs as a single person - you can survive and thrive - infact you're middle class. 5 dollars is what world bank use for upper middle class.
Next is this "producing goods and services" - for me - whatever you do to earn a living - do it - if it's being in the transport sector- boda boda - you're producing transport services - moving goods and services.
Otherwise it dogmatic to imagine we should "manufacture" stuff - people should figure out how to hussle - get 500shs and survive with it - till tomorrow. Delay child bearing.
Kenya is truly a very poor country that's why kadogo economy is thriving. The only way out of poverty is production of goods and provision of services.
