The study recommended thatin order to guarantee that the education sector receives accurate funding allotted, policymakers should develop and put into effect suitable policies that will make the money allocated to it transparent. The government should make sure that only authentic medications and equipment are purchased and maintained, and health officer staff members should be motivated to carry out their duties with efficacy and efficiency. Doing so will significantly boost the amount of health development in the nation and raise productivity. Politicians and other policymakers must make sure that Nigeria’s debt is not taken on for personal gain or political gain, but rather to boost the country’s economy and guarantee that loan payments are made on schedule and in full.
