Can governments cut their deficits?

Yes says Don Marron who produces these past deficit reductions from his research:

1. Ireland (20%, 1978-89)
2. Sweden (13%, 1993-2000)
3. Finland (13%, 1993-2000)
4. Sweden (13%, 1980-87)
5. Denmark (12%, 1982-86)
6. Greece (12%, 1989-95)
7. Israel (11%, 1980-83)
8. Belgium (11%, 1983-1998)
9. Canada (10%, 1985-99)

Greece can do it, they've done it before, more than once.
