Is Chicago a "sanctuary" (don't ask, don't tell, regarding immigrations status) for illegal aliens?
I bet that most of those who voted for this are also in favor illegal immigrants.
If you want a "living wage" for unskilled/low skilled work there is a simple solution ... secure the border, build a wall and stop importing massive numbers of poor, unskilled, and illiterate.
Outside of Southern Cal and Texas, Chicago probably has the most illegals of any city in America.
