Let me tell you a story about Detroit. Once upon a time, cars were made in Detroit. Because of the cars, people had good jobs. They could afford a good lifestyle, with college for the kids and maybe a cottage up north. People flocked to Detroit from all corners of the US of A (and world) for these opportunities. And then the jobs left. They went to China or Mexico. The jobs that remained gave lower wages with fewer benefits so that no one had any money anymore. Buildings crumbled. A lot of people moved out of the city. Housing prices plummeted. Businesses suffered.
