That's fine - I wouldn't move either if I was lucky enough to have a family. But for people who put their company above all else (not recommended, having done so), it's an irrational decision to stay if you want funding. Everyone here bemoans the terrible funding environment. We can't even get a YC ripoff here.
I know for certain there is money in Chicago... It's not meant for software startups, but you can find healthy sized Angel investors / investor funds there that are interested in fishing.
