It's not just the policies, destructive as they are. It's the way Obama is constantly running down business people as individuals.
The reason this economy is not recovering is that the entrepreneurial function has gone dormant. People still have as many productive ideas as ever, they just aren't acting on them. Why should they, when succeeding will only make them a target? This is why, unlike with most presidents, we should hold Obama personally responsible for the weakness of the economy.
