Yes. I've responded multiple times in this thread, right? ;)
If I can buy one used Ford and support five third world kids through Compassion, but the three gold plated trucks will keep me from even dropping a buck in the Salvation Army kettle, then there's good I'm leaving undone just so I can have three gold plated trucks instead of one truck that's painted red or blue.
What if you can get by with less then the used Ford and help 10 kids in a 3rd world country? The Communist would call you greedy. In their world, anything more then meeting a need is greed.
So what? The commies also say I'm not a slave if the state owns everything and that if you kill the Romanov kids in a basement that's just what they deserved.
The important thing here is that there is greed and there is self-interest that isn't greedy. Saying that there's not a line either makes greed good--which is amoral and violates common sense--or makes legitimate self-interest into an evil. Both feed into anti-free market mentalities.
