If only we had built walls around them earlier.
We could throw masks over the wall to them and go about our business.
Decades ago the right wing L. Brooks Patterson of Blessed Memory said "We ought to build a wall along Eight Mile Road, a physical wall. Keep the crime in the City of Detroit if they want it but stay out of Oakland County."
The new idea of a wall was shocking to the liberal press and grandstanding pols then. Crime fighting was called "racist."
Then the remaining non persons of color in Detroit moved out in the record "white flight" recorded in the US. Over 82% non-white Detroit population most years after then. If these liberals weren't hypocrites they would have stayed inside Detroit and suffered to promote their causes. No way. Wealth shifted to the suburbs.
All the expense of moving, building new water and sewer and electric lines and landline phone lines plus stores and so on, all to escape Detroit.
