You can continue pulling figures from wherever. Just know Kenya would have collapsed a long time ago if a third of its people had no monthly income.
Perhaps the schools in Tanzania did not teach you the meaning of informal, so let me explain.
Informal in this case means not following the usual laid down procedures. That means no government licenses, no banking details, no income tax etc. These are among the indicators of employment.
When these are unavailable, the government and other bodies will conclude that it translates to unemployment.
The reality is millions of these 'unemployed' Kenyans live quite comfortable lives, hustling everyday without bothering the government.
But of course from your office internet you cannot know that. The sooner you quit being an armchair economist the better for your village.
And you may deny it all you want, but the only reputation Tanzania has is laziness. How can a sane country go for decades without wars, dictatorship, famine or any major problem and still rank among the world's poorest.
Laziness is a culture that starts from childhood, and Tanzania will need many years to eliminate that.
While Kenya's biggest problem is corruption, Tanzania's is laziness. Which I consider to be much worse.
And the thing is, it's not just Kenyans who comment on your laziness and work ethics.

this thread on Quora to read some comments from some expatriates.
The first stage of moving forward is looking back and acknowledging your flaws.
In your case it's very simple.
1. Tanzania is bigger, with more natural resources, yet poorer than Kenya.
2. The gap between the GDPs of Kenya and Tanzania continues to expand.
3. Kenya with all the resource disadvantages still has an annual budget nearly double that of Tanzania.
4. Tanzania has been peaceful for many years, but that has not translated to economic growth. Why?
4. Why does everyone think Tanzanians are lazy. Is there some truth?
Once you answer those and other questions, you'll be on the path to success.
Kenyans also have many questions to ask themselves.
