The last update said that Larian is working on a mod for the economy, although I think it primarily is to reduce the value of common items, make cool items rarer but more valuable, and so on.
I was surprised to hear that some people even steal items worth 3 gold. I mean, who has the time to do that?
I didn't bother stealing anything in my playthrough, I couldn't be bothered. Sure, money was a little tight at times in Cyseal, but after a while, there amount of loot you get means even a non-stealer will get a ton of gold. So I think that Larian's approach is a sensible one.
