> They learn that life is completely unpredictable
As someone with pretty much the upbringing you described, I don't think this was the takeaway.
For me personally, I learnt adaptability, how to adjust to new situations and people quickly.
I saw what my parents did and said "I don't want to be like that".
The downside is, it's hard to answer "where are you from?", or to know where home is, and it's especially frustrating as an adult to see your parents continue to make bad decisions, to continue to be broke etc.
I know everyone is different, but anecdotally my sister and brother also seem to be doing relatively well.
i also had a lot of that (except for the bad decisions and lack of planning) and i also became adaptable. what i didn't learn was attachment. and it took me decades of my adult life to understand that, realize how it affects me, where it came from, and i still don't know what to do about it. my brother on the other hand suffered from depression. despite being very similar in age and thus similar experience the outcome was very different.
