Yeah... I wish '70s-era Christians would read Snopes' entry about the claim that Jimi Hendrix called Phil Keaggy the greatest guitarist alive. (Though, admittedly, he is currently more animated than Jimi.)

By any objective, historical perspective we are are rich.
However, many of us are stressed.
That's the real struggle: To become, like Paul, content with both much and little.
Most western Christians need to deal with their inner conflicts about money, i.e. baggage and presumption.
Rather than the rich/poor measure, we should be working to get healthy about money.
