Chicago is having a Construction boom.
But there are few, if any Black African American construction workers on local (Hyde Park) construction projects.
The workers seem to be a 50-50% split between White - mostly older union workers and young Hispanics. Why is this so?
Chicago Black AA public schools no longer feature "trade school" education. The handy man type of training work is now all done by "undocumented" Hispanics and when the undocumented become citizens they have ethnic connections in trade unions and it's a natural transition.
Many occupations that were once dominated by English speaking, native born and raised Black A. A. are now overwhelmingly Hispanic - jobs like cooks, bus boys, landscapers and especially nannies. Open borders advocates (the entire Illinois Congressional Delegation led by Sen. Dick Durban) always argue that the "undocumented"/Illegal aliens only do the jobs legal Americans don't want. But, if these jobs paid a higher, living wage - then native born Americans would take them.
The entire Black Congressional Caucus gets F immigration grades from NumbersUSA and go with the idea that mass immigration from Mexico and Central America is a good thing because these people will all vote Lib Democrat.
Since I lived in Southern California I noted that Hispanics have pushed out Black AA from historic places like Watts and Compton CA - and also taken over these service jobs once done by Black Americans. So far the Chicago Democrat machine has gerrymandered Aldermanic and Congressional districts to keep Black seats, but since Chicago the city has lost ~ 50% of it's Black AA population since 2000 - it's inevitable that many/most Black aldermanic and Congressional seats will turn to Hispanic.
I also go with the idea that Chicago should not be a city in anarchy where laws against illegal immigration, hard drug trafficking and human trafficking (slavery) are not enforced as are our laws against shootings and murder.
