Books have been written about this. No place on earth since the Exodus from Egypt has the population shifted so quickly or dramatically.

Detroit will continue to lose population until our society as a whole changes, which won't be anytime soon. Such as:

When races and religions decide it's OK to live next door to each other. Remove the walls of polarization and racial politics.

When the gap between rich and poor has shrunken.

When the birthright of all Americans is a socialized health care system based on the Swedish model, and when a free public education means a quality one.

When American coroprations are required to employ Americans by quota before they can expand overseas.

When the federal government returns to a tarrif based foreign trade system.

When we return to a1950's domestic personal tax policy of taxing income over 2 million per year at 90 percent, to stop the practice of legacy wealth from creating generations of lazy, entitiled people from sitting on their backsides and day trading on their laptops by the pool.

Only with new federal policies, and local elected officials held accountable for their nonsense, will employment increase, education improve, and the promise of a city and country with a future become reality.
