Going by diet, the nigger consumes overall more food than a pajeet. It therefore stands to reason that a nigger will shit in the streets more than a pajeet individually.
The pajeets get shit for their "designated shitting streets", and overall do more street-shitting by volume, but that's a mark of local poverty (quite literally the "purely socioeconomic factors" cope for niggers) forcing them to try and keep the rest of their streets clean.
