A tutor aids people, most notably those whose parents cannot, in education.
You think most of our economy is meaningful? If we got rid of half the jobs that are based around utter crap- luxury items, meaningless services, etc., the unemployment rate would skyrocket. Why should job based around aiding the poor be considered somehow less worthy? Would people give donations to your church if all it did was preach and it never did anything for the poor? Now true, we'd be better off if no one was poor, but that is a bit unrealistic. And contrary to what cynical cons like yourself may believe, the people who work for such causes would rather see poverty end as well (obviously if poverty was eliminated, they'd be able to apply their skills elsewhere). I'd rather see people use the existance of poverty as a creator for jobs (keeping less people unemployed) and a builder of character through doing good than as an excuse for people to look down on one another when they pretend poverty is a person's decision.
