Investment in lower crime ridden areas goes up, unemployment goes down, crime goes down. Quality of life goes up, Policing becomes more focused and crime falls or fewer police needed so taxes go down again.
Who suffers other than criminals?
Sounds nice in theory; the problem is that prison is a pretty ineffective weapon in the fight against crime. It works when the criminals are still in prison but what when they come out?
Reoffending rates are very high, according to the Prison Reform Trust, 67% of prisoners re-offend within in two years, in 1995 (when a get-tough prison policy was introduced, the reoffending rate was 56%). So unless you keep people in prison for massively long sentences, the crime rate will stubbornly refuse to go down.
You should learn from history: punishment in the 18th and early 19th century was savage: people were hanged or transported for minor thefts yet crime stubbornly refused to go away. These days one could walk from one end of London to another with little chance of being attacked, something that would have been impossible 200 years ago.
