I don't agree that there's any real link between crime and the state of the economy. Crime rose for decades whether the economy did well or not. The economy was booming in the late 1980s as crime went through the roof.
The aspect of the economy which effects crime is the well being of the lower classes - in other words income distribution. This has almost nothing to do with whether the 'economy is booming' or not.
And certainly any economic 'boom' of the late eighties did not trickle down on the great majority of people. Those years were very bad for the poor and working class.
