That's right, but the second generation doesn't have to be the one paying it back, but it's the doings of first generation and they must be so cruel and idiots that they only thought about themselves and their coming generation is now slave. But this system is old and is not practised in most of the world, but only in progressing countries, for examples, here in my country if a poor person took loan and died then his children have to pay for that loan but it's not like the parent used that money for enjoyment.

Loan should never be taken, and it should never be inherited to the siblings but unfortunately the world has been shaped in a way that, all the loans are not responsibility of their upcoming generations.
