I've been in and around Christian communities my whole life. There is truth to what you say - someone being Christian increases the likelihood that other Christians would be willing to help them.

But by and large the prevailing attitude is even more disappointing and unchristlike. People are simply selfish and only want to serve themselves, keeping every penny they have earned regardless of those in need around them.

The rich don't get rich by giving it away, and this is well known amongst the rich themselves. Some may even give on a personal level, giving them a visual alibi for using their resources politically to actively oppose legislation and policy that benefits those less fortunate. To me this is even more evil.
