Its very simple just slice the budget and enforce stringent financial management to reduce excesses.
Take a look at the Auditor-General's report for any one of the last few years. The major thefts---NYS
gunias of cash in basements etc.---are well known. Lesser known is the thieving that is all over the place. I did some quick sums on last year's report, and, even with rough calculations, it looked like well over 20% in the year was either stolen directly (money just disappeared) or indirectly (paying, say, 20K shillings for something that actually costs 2K shillings).
What you propose, which makes a great deal of sense, cannot happen right now ... unless you have it mind that the eaters will suddenly become herbivores.
