How should we help others who are less fortunate?

Welfare is organized charity, funneled through the collective, the government. But it raises many issues. How should we help others who are less fortunate? Can we differentiate between the "deserving poor" and the "undeserving" poor? When is helping someone really helping them, and when is it rescuing them and enabling their own self-defeating behavioral patterns. Can beggars be choosers? Are any "rights" implicitly forfeited by someone who receives charity? For example, if offered work, is the person who is given welfare obligated to accept that job, even if they don't like that work? What if the decision as to a job being not acceptable is viewed as trivial or unworthy by others?
