Never heard of the study. But If I had of, I would not have believed it based on my life's experience and the experiences of my catholic school peers. Charitable acts of all ,whether it be donating your time or your money was common practice. And Lord knows the church has its hands in a zillion operations :)
In my graduating class of 96 students, there were 5 volunteer firefighters.
Three of us ran Rescue Squad calls (EMS) also.
Yes, it was a Catholic School.
You see, we had been taught from an early age to 'walk a mile in that other person's shoes', and it is my firm belief that it made us more generous, of both our time and money.
But that, unlike socialist programs that rob the people at gunpoint and throw that money to the four winds often enabling bad life choices, came with the discretion to see that our efforts actually were doing good and not causing more harm as well.
Now, to the Socialist, not giving a junkie a fix might seem cruel, asking someone to get a job might be mean, but I believe if you give a man a fish, he'll eat for a day, teach him to fish, he can eat for a lifetime, if he gets off his ass and goes fishing.
