It's not that poverty causes all crime. Wealthy people commit different crimes than poor people. [1]
You bring up the 2008 recession, but the poverty rate, rose from ~12% to ~15%[2]. A meaningful but not earth-moving change. Median wages did not decrease [3], suggesting that the rise in poverty would be from job loss, which has not been shown to have a simplistic, direct relationship to crime [4]. The fact that poverty is not the most important factor in crime does not mean it is not a factor.
That is all to say - poverty (and in a wider sense forms of desperation) are not the sole force driving crime, but they are a force for certain crimes. Again, it's very reliable that you can reduce crime with better social support. That's not to say that crime == poverty, just that it's one of many factors that influence people.
