This is very true. In the 80's and 90's there were a handful of these "Tel-evangelists" that made the bad rap for pastors who are truly following God's call on their lives. I define a pastor as a man who feels God has placed a calling on his life to preach his word to the lost, or a congregation. But as a result is sacrificing "things" of this world to better God's kingdom through themselves. So a pastor can have a nice car, but a Mercades or Cadillac is "unnecessary". As for a lot of things in their lives. People just seem to take a minister more seriously if he is sacrificing in his own life, and leading by example.
I happen to be very opinionated and up To snuff on what the Bible says a minister's life should be, (read 1st Timothy) because we had a Evangelist take over as pastor in our church about 5 years ago. After finding out he drained all of our accounts, and cut spending to missionaries completely, but yet was able to afford a Mercedes, and a home in a closed gate community, we had left the church. Then when the rest of the congregation found out, he was canned. Turns out he had also re-financed our church's building three times in the two years he was there also, so he made out with a lot of cash.
But his judgement, like all of ours will come.
