Federalism is the only solution. The alternative is statisticians at treasury calculating poverty indexes that are heavily eschewed. Most livestock rearing counties are deemed poor but they're quite wealthy. A Samburu with 50 cows and 100 goats is several times richer than a poor peasant kikuyu with 1 acre. Even though the kikuyu is deemed richer cause he might have modern amenities like a proper house, water and electricity.
