Some do, of course. I said the more educated you get, meaning that at one point you have to question yourself believing in something that is not tangible and where science has proven otherwise.
If you look at the evangelists in this country, or even the Vatican outside this country - they're all rich beyond their means from preaching "God's word".
Just like in the middle ages, they take advantage of believers, they take their money and continue preaching. That's their livelihood, of course they won't stop, they misuse the trust received by believers to gain wealth. Most of them are highly educated, but do they believe in God while taking advantage of others? You be the judge of that!
