It comes with middle class life. Most Kalenjin have or had large fertile land that can sustain you without the need to put in daily labour. The free time they use to drink. So you plant maize in 3-5 acres - then drink - sell maize - pay school fees - back to drinking. It also a problem in kiambu because you now have hot money from selling plots of land - then you spend the whole year drinking - then sell the land.
Communities like Luo or Luhya are too poor to afford to drink daily without going to work. They have to go to Kibarua - work so they can eat. Kalenjin in meantime has enough food in the store to last a year, has cows to bring milk and some for selling, and extra maize for selling to for large expense. The rest of the year is sherehe ya pombe from morning till evening. Guys take a lunch break
- find food ready - then resume to sherehe-
But as land parcels become smaller - then such lifestyle is no longer sustainable - lazima labour intensive living.
Kales are the worst drunks in Kenya. Every time I inquire about the Kales I knew from school, college or work in Kenya, they are either dead or broke and jobless in Kenya and most likely blaming the government for all their problems.
