I think you made valid points there. I‘m not familiar with any of the anti bankruptcy measures you just named. Sounds like your family did their research.
To be honest, I still dont think your family is the problem but I dont feel like this is a fair discussion among equals.
I said my piece and you questioning my motives kind of unnerves me. Is your family privileged? Absolutely! Is it fair to the others that they are able to buy homes and even keep them if they fucked up financially while most other lose everything? Not in my opinion.
But I‘m still not after families that try to secure their childrens future. As a privileged person, you might want to add some empathy to your answers in the future.
