Most immigrants usually have insular communities and have their own micro economies and communities so it's not like that the money flows to the broader Black community.
Idk what city you're from but in mine (Brooklyn), this is absolutely not true.
1. You won't see insular black groups e.g. Jamaicans only doing business with Jamaicans. Everyone is doing business with everyone. There aren't any neighborhoods here that have only one group. It is a nice mix, so everyone is FORCED to deal with each other.
2. They barely have money flowing to their own "micro-economies". The money of ALL black peoples flows to Jews and cacs mostly.
3. People don't live online. shyt is hard out here. The average black immigrant isn't writing articles about us or playing us in movies. People are just trying to pay bills and eat.
4. Personal anecdote: My Caribbean neighbors have always looked out for my family, financially or otherwise and vice versa. So on a micro level there are likely many instances of black immigrants benefiting us.
You guys have to get off the internet for a bit.
