Yeah. Because everyone is stealing just one loaf of bread to feed their family, right?
No, but young underemployed men are actually a menace to society because they tend to get 'creative' when confronted with an unsatisfactory future, or too much free time. When presented with 25/hrs a week at Timmy Ho Ho's, or when they have no prospects at all, bad things happen. That's pretty much been shown to be the root of almost all preventable crime, and it costs everybody a fortune. Cudos to the guy with high school diploma and 3 part time jobs @ $11/hr, but a lot of men wouldn't make that choice. People can say 'personal responsibility' all they want, and like 'abstinence', a certain amount of lip service CAN BE GOOD, but if you take the notion too seriously you actually end up causing real harm, and causing outcomes that have real big costs.
It far cheaper to have robust before and after school programs (in and out of schools), summer programs, summer student employment subsidies, reasonable equality in public education, help to make sure an adult is 'at home' in the evenings, to encourage mixed income communities where possible, access to post secondary education, AND ACTUAL DECENT PAYING JOBS for young men (and it is young men specifically). That's what kills preventable crime cheaply.
