I know many wealthy people. And it's true that they can lose their wealth through bad decisions and unfortunate circumstances. However, nearly every wealthy person I've seen this happen to has regained most of their wealth. Why? Because once you're wealthy you have connections to other wealthy people. Their friends will build them up again. Reaching the status of "wealthy" is a sticky bit. As long as you don't alienate your other wealthy friends, you'll retain your wealthy status.
That maxim you hear is true: the first million is the hardest. After that you're set.
