North Carolina is purple but it's still relatively red. Same with Florida. Same with Georgia. Texas is still red. Charlotte, Atlanta, Dallas, Houston, Austin. Those are among the fastest growing cities.
I wouldn't call Georgia purple, but those cities are growing from the influx of younger people leaving NE/California, and consequently turned those States as Florida and N. Carolina purple. Consequently, the economies of each has grown, but you've highlighted three or four States, plus Illinois in the oppsitte direction, which still doesn't negate the strong relevance of blue States on average having stronger economies than Red States
