Just like termites.
I lived in Tulsa in the early 80s. The recession was hitting some of the northern and northeast states. Tulsa’s unemployment rate was about 2.8%.
The Tulsa Mayor went on TV and exclaimed to those in the northern states: ‘We have jobs! Come on down!’
And they did.
Every 3rd vehicle on the streets was an out-of-stater. Most were from Illinois and Michigan, but other states were represented.
By about 1983/84 the recession was hitting Tulsa. Unemployment shot up. You couldn’t BUY a job at McDonald’s. The ‘official’ UE rate was nearly 9% and the ‘unofficial’ UE was nearer 13%.
It took Tulsa nearly 2 decades to recover.
