How rich is too rich Dave? This is a big reason why i think many less get into Heaven than most Christians think.
Jesus was pretty much a free willing hippie, yet it seems that material things mean more to humans because they get things they don't need.
I will preface your response by saying, yes I know you don't know how God thinks/judges etc. I just want your opinion on it as a man of faith and I think reasonable means? (I don't know on the last one just assuming, I know you work in insurance).
I think probably "sufficient" is different to my needs than it is to your needs. Refer back to Jesus' narrative about the vineyard owner in Matthew 20. Essentially, he paid the guys hired late in the afternoon the exact same day's wages as he paid those that showed up first thing in the morning. When the early birds complained, the vineyard owner's response was "hey, it's my money, what's it to you if I want to pay them the same as I paid you? Also, did I short change you at all? Did I give you what I promised to give you?
So I put the questions to you (and then I'll give you my opinions):
What's it to you what a given preacher makes? I COMPLETELY understand if the guy is cheating people or lying to them or some other manner of malfeasance, in those cases, lock him up as far as I'm concerned. But by and large, Scripture teaches a worker is worth the wages he is able to command and it doesn't reduce my wages at all that such and thus preacher makes more than I do. My employer pays me what they agreed to pay me (and, to be quite honest, I make almost twice what my pastor makes ... and definitely more than twice what our associate pastors make so that's not a fair analogy, really).
So let's take Rick Warren for example (I have no idea how much he makes), so he gets his pastor's salary whatever that is, but he also has a ton of cash rolling in for his speaking engagements and the books he writes so I think it's safe to say the man is comfortable. Is that unfair JUST because he's a preacher? Well, like I said, I don't know how much he makes. NOWHERE in the Bible does it stipulate that to be a Christian, you have to dress in robes and walk from town to town living off the largesse of others, without a penny to your name. ON the other hand, no one said preachers should be millionaires, either.
I do believe some of these guys will be held accountable to God, Himself, when they stand before Him at the judgement. Some of these guys (Oral Roberts comes to mine) will, in my opinion, have to stand before the Creator of the Universe and justify how he spent God's money.
The Bible tells us to support our pastors, and to give to widows and orphans, and to build His church (not necessarily the building we call church, but "His Church," universal.
So, all that to say, I don't know what is sufficient for each individual pastor, but I know what is sufficient for our pastors because I'm on the board and we've researched it both through our community and through our denomination and, believe me, they will all have to save for a VERY long time before any of them becomes a millionaire (in fact, up until 3 or 4 years ago, I was insisting that the board raise our pastor's salaries so their wives didn't have to work outside the home... but that's another story).
I'm sure there are preachers out there who are phonies and charlatans, but they don't have to answer to me, though they definitely WILL answer to God because we all have to.
