Let's say you had no-strings-attached money to spend to spur growth, benefit the current citizens of the city of Detroit...and encourage people to move back?

How would you best spend $10,000?

1 Million?

10 Million?

100 Million?

1 Billion?

100 Billion?

I'd love to hear some creative ideas at all levels.
