In a system where economic advantages agglomerate in a few areas, it would be difficult to create a place that is neither losing to the agglomerating areas, nor is declining itself.
If it is an area where the economy is booming, then it will not be cheap. And if it is not an area that is moving upward, then it is moving downward, and with that comes a host of issues that can cause crime to proliferate.
> Ford Model T cost $260 in 1925 ($4561 in current USD). But today's cars are closer to $40k.
Far more capable and safer vehicles than a ford model T are available for far less than $40k. $20k cars are available, and while not quantifiably true, I think it is easy to say the $20k car of today is easily more than 4x capable and able to provide utility than a $4.5k model T.
