Is this Moral Failure?

Introduction
(selling out)

"I think the term "product" has a bad rap. I blame Wal-Mart."
"I think Wal-Mart is evil enough to dwarf the combined sin of the rest of mankind to nothing (in comparison)."
"Wal-Mart is 'selling out' incarnate. Sold out and morally bankrupt."

Yay for shopping at Wal-Mart...
...because the ethical implications of doing so just don't weigh heavily enough on the average middle-class American conscience (conscience? what conscience? that would involve some mechanism of internal reflection. we are too approval-seeking to have developed anything like a conscience.).

The Good Samaritan Experiment
"In the Good Samaritan experiment, even seminary students could not be counted on to stop and help a stranger in need. In the experiment, Princeton seminarians were asked to prepare a report on the parable of the Good Samaritan in one building and report to another building to discuss the parable. The seminarians were randomly assigned to one of three groups, those told that they were running late, right on time, and a little early. While making their way to the other building, each of the seminarians encountered a man slumped on the sidewalk in obvious distress. Of the seminarians told they were early, 63% stopped to help; those on time stopped 45% of the time; and 10% of those running late helped. The researchers found that, "Ironically, a person in a hurry is less likely to help people, even if he is going to speak on the parable of the Good Samaritan. (Some literally stepped over the victim on their way to the next building!) The results seem to show that thinking about norms does not imply that one will act on them.'"

Moral Care
Why don't we care?
...about large scale exploitation,
starving children in other countries,
foreign wars...
..when none of it affects our immediate interests and well-being?
Why isn't it of interest to us!?
Sometimes we feel somewhat guilty about it, but not enough to move us to action.

Only small minority of us are in the humanitarian "business." Why?
We could all contribute something, and, likely, more than we are.

Moral Obligation
Why don't I look into everything I buy so as to boycott goods from exploitative companies? Why do I eat meat? (Because it's customary and I'm used to it and it would be inconvenient to do otherwise?) Why don't I give money to every television add for charity? Why am I not devoting my life humanitarian causes?

Is this moral failure?
Or is all of the above supererogatory!?
Certainly I am concerned about all of these things, but why haven't I really tackled any of them with more...gusto?
Am I alone in feeling this way?
I keep settling on the idea that I should concentrate moral efforts locally. I should do good where I am.
But then in today's world is there really any excuse for not thinking globally?

It feels like such a battle. I'm one of those people who, when he becomes really passionate about something, devotes all his energy to a single thing. So how do you juggle these global issues with personal life goals. How can anyone have the energy for all of this in life? I guess one ought to find some way to compromise?

Two things:
(1) What moral obligations do you think we have?
(2) Any of the issues I mentioned are up for discussion as well.
