I've heard their names mentioned many times. You may be on to something; with that said,
I would seek to add another category besides just their wealth. Remember Job was very wealthy
and God blessed him with great wealth as He was a generous man and give to many.
Therefore simply looking at the wealth of someone who professes to be a follower of God is not enough to hold
them suspect before the body of Christ, I would inquire about their giving, and their lifestyle. Some have millions
and use that to set up foundations and hospitals, Christian schools, etc, etc.
I'm not defending anyone of the names you've listed, just throwing out a point of consideration.
