It is generally unsustainable for a sacco to give dividends at above 12% sinnce that is the interest rate they apply on loans.So you sometimes find that some are (1)borrowing loans to pay dividend (2)depleting their general reserves to pay dividends.
I sometimes also feel that the main aim of joining your sacco is to get a loan to fund your own serious investments instead of celebrating those dividends received.
Formally employed people often live their employers' dream & forget about their own.
