Well, that really depends on the society. I don’t live in one that makes such assumptions. It feels a little bit entitled to assume something like that, but that could also just be cultural differences between developed and non-developed countries. The former have social security and safety nets, rendering an inheritance less important and much less prominent. Feels like the only inheritance worth even thinking about is if you have millions in excess of what you need for living, and in developed countries that is very much less prominent than in developing countries
Unless they’re the sole recipient of a will (doesn’t seem very common), at least here those are almost always liquified and proceeds split according to the will. Doesn’t amount to much usually, though it might be different in countries that have very large and expensive cities.
