I listened to the full interview and he said quite a few things, but I want to focus on two main points he brought up:
On Taxes:
According to Omtata, Kibaki raised the KRA revenues by 1 trillion over the course of 10 years; Uhuru did the same over the course of 10 years. Ruto is trying to do the same, but in one year and according to OMtata, this will be mathematically impossible.
Omtata is saying that Ruto is trying to fix the debt problem that uhuru left behind, but he cannot expect to do it by raising taxes in one year
On Debt:
Omtata has said that he has studied the mozambiqan example and kenya is in the same category. Kenya is loaded with odious debt that was never used for the benefit of the people but that was instead stolen for the benefit of a few individuals.
Omtata has said that his next case will deal with this issue of odius debt that he doesn't believe the kenyan taxpayers must pay back because they never benefitted from it. Rather, those who stole should be prosecuted even in europe if need be and that is going to be his next case. Jimmy Wanjigi has also made the same statement. Instead of trying to pay off this debt, ruto should follow the mozambican example and declare it odious and not pay.
