I don't think escapism actually escapes anything. The US welfare state is escapism from a certain view point. However, the people in it are pretty much locked in place by the system. They are also locked out of "good places". I conjecture this is what causes the crime rate among that same population. They see little opportunity to improve their lot by any means other than violence.

There's some research[1] showing that video game escapism reduce crime. Other research show that porn reduces sexual crimes.

Add to that the free use of marijuana (which generally decreases motivation ) , the better capabilities of police enforcing crimes, the possible growing acceptance of unemployment in an automated society, you'll see even further reductions.
