I admit that's unfortunate. I don't think that was a "bad deal" in the sense that anyone grievously misled you or anything.
I would feel bummed out, but not angry or like I actually got ripped off, in other words. When I signed up for the 20-year term, part of what I was being asked to do was estimate how likely I think it is for this firm to actually be around for that full 20 years. That's just part of the game.
