Trying to be vague for privacy reasons, but left CA 35ish years ago (had someone expose himself to me in my front yard) and have been back half a dozen times since then. Each time, the decline was very observable. The time before last, I was in Chinatown in San Francisco and the store owners followed me around. My favorite restaurant was filthy and had an extra charge on the bill to cover employee health insurance. My beloved Fisherman’s Wharf was dirty and had signs everywhere warning about car break-ins.
The last time I visited, we flew in to Sacramento, went straight to Yosemite and Kings Canyon, and left. I have no desire to ever visit CA again. And we have relatives there.
So according to your logic, the entire state of Texas is garbage because of Austin
