An announcement 5 or 6 weeks ago is hardly old news. It is news to me because I just read this. I am sure that there are others who have not read this also. The significance is not so much about the one company, Caterpillar, as the trend to move businesses to the big cities.
We are still subject to filtered and fake news.
Caterpiller here in the Pittsburgh area failed a year or two ago, I don't know why, but to make a move to Chicago looks an awful lot like the last gasp before go8ing under.
