Community service and volunteer programs are setup to help unemployed people so we're telling unemployed people to help other unemployed people.
This is despicable because we have to remember that nobody asks to be born into society. It's the same reason we prohibit child abuse and child labor, make parents take responsibility for the delinquency of their children, graduate children into adulthood only after periods of time, and require proficiency before getting licensed.
If someone is unemployed, that means society has failed to teach the unemployed social values, and allowed labor supply and demand to become desynchronized from social decay. People were allowed to reproduce without having commitment to their children's networking into becoming productive.
As a conservative, you should realize that social values come first, not industry. Industry is the result of people being thoughtful. By demanding people work for unemployment benefits, we're saying it's OK that parents and administrators weren't thoughtful in planning ahead what it would take for children to fit in.
