I have noticed that. Long ago I belonged to a church in which an elder told me the rich have their money not through honest ways or something to that effect.
At the time I dismissed his comment as either jealous of ones with a better life than he or as suspicious because ones without always seems to be suspicious of ones with.
But that comment has rippled through my thoughts over the years so many times and I wonder if indeed he was right.
In many cases no doubt he was right. However Dr. Tom Stanley made a decent living referencing types of people who do it honestly through hard work and living below their means.
