>having thieves steal their money if they got too rich

Money attracts that kind of thing, even in the real world. There's a reason rich people have guards. Also bodyguards - I was just listening to a podcast about how a fairly rich (and flashy) drug dealer got kidnapped and ransomed because he didn't think about what a target he was. Obviously more challenging when you're talking about heroes who are personally formidable, but think about friends, family members, retainers, etc.
