In other words, middle-class employed people who are safe in their environment don't really commit crimes - why would they? The best way to solve crime In General is to make more people like that.
Now granted, there are some people that would _still_ commit crimes even though they don't need to - this is the place where punitive solutions are appropriate, to make it not worth their while.
> Based on these estimates, the observed 2 percentage point decline in the U.S unemployment rate between 1991 and 2001 can explain an estimated 2 percent decline in property crime (out of an observed drop of almost 30 percent), but no change in violent crime or homicide. The sharp increases in crime in the 1960s—a decade of strong economic growth—further corroborate the weak link between macroeconomics and crime.
Violent crime rates started trending up in the 1960s, more than doubling by 1971: https://lh3.googleusercontent.com/U0YlrTTCYi550Z4py1MNVenNt-...
Meanwhile, the economy was quite strong until 1969, with unemployment below 4%: https://fas.org/sgp/crs/misc/RL33069.pdf (p. 5). Poverty rates went down about 40% from 1960-1970, and then were stable until about 1980. Over that same period, violent crime tripled. From 1982 to 1990, poverty went down by 15% and unemployment dropped in half, but violent crime increased 36% to historical peaks.
I wouldn’t expect homicide to meaningfully drop in an economic boom since the reasons for murder are so varied.
This seems impossible to solve without considering which people were actually experiencing this growth.
> In 2013, for example, the average poverty threshold for an individual living alone was $11,888; for a two-person family, $15,142; and for a family of four, $23,834.7
I wasn't alive in 1969, but for 2013, that threshold is quite low - it may make sense for poverty, but it is not a net wide enough to catch a significant portion of (relatively) poor people whose addictions have grown to far outweigh their paychecks.
A little silly but also nice.
There is also a middle ground, where you can think that drugs should generally be legalized, but incarcerating people for non-drug crimes is a good idea. The problem isn't really people doing drugs. It's people breaking into cars, damaging property left in public, trespassing, assaulting other people, leaving big public piles of trash, things that fall into the "harming other people" category of crime.
