The bad folks are 10 percent. 90 percent are decent
I think it's the opposite actually (most kenyan men if separated from their wives or girlfriends do not provide any financial assistance)
Ruto and Gachagua can begin by highlighting these issues in their speeches. Start telling men to stop wasting their lives drinking; to stop being deadbeats (gachagua especially seems to be a family man and he can push this message) and they need to start using the word "dead beat" and shaming these men.
It is a societal crisis when men are completely removed from the upbringing of their children and from work and productivity and think it's okay to go having baby's with 5 different women none of whom they can support.
