Who had more reason to leave their home country - Italians of the 1910's or African-Americans today?

In the early 1900's, millions of Italians left the only country they knew, where they had heritage going back to Roman times, to settle into a completely new foreign country where they didn't know the language. And why did they leave? Because the economy wasn't doing well?
African Americans of today report that they are the victims of rampant police brutality, that U.S. hospitals are part of a conspiracy to harm them, that there is a school to prison pipeline, that the CIA purposely introduced crack cocaine into their community to kill them, and that 20 million of their people died in the trans-Atlantic slave trade. 
My question is: who had more of a reason to leave their home country?
