That's really what you get with booming economies, principles of free enterprise, market capitalism and it's hard to get around that.
The states with the largest economies are California, and then, Texas, New York, Florida and Illinois, I don't know the exact order but one can make observations from this.
It's not that, in Europe, Merkel just loved to see Muslim refugees come in, it's pretty clear that the UK, Germany, etc. have very strong economies but not a good replacement rate.
In the meantime, some sluggish states such as West Virginia for example, will continue steadily as they are.
The best that can be done might be to control immigration; but I"m not sure how well that will work out in the long run, say over 5 decades.
