Teachers until recently earned 17K so did our police force and they constitute the bulk of civil servants...so yeah average salary of 12k for 200K is a lot of "money"... .those guys are definitely able to escape the international poverty line (2 usd dollar per day)..which is 60 dollars per month.
To my mind, someone earning Sh. 12 K per month in Kenya is poor. Quite poor. But, I don't live in Kenya, and that is just my impression from looking around on the few occasions when I visit. Also, as you note, just look at the international poverty line!
If Sh. 12K per month is a lot of money, then, yes, people are definitely going great. Perhaps we finally have a solution to the huge unemployment problem in Kenya? If so, then I'm all for it!
