I’m fairly certain people of all classes, ranks, and social situations in ancient Mesopotamia, China, India, and Egypt sometimes swept ‘unpleasant’ grief under the carpet too… unless you have some credible reason to believe otherwise?
The proportion of multi-generational homes in modern western cultures is far lower, and the emphasis on taking care of your parents as a sacred social duty is gone. I'm sure that there were plenty of individuals in those historic cultures who fell short of what was expected, but widespread care homes are a relatively recent change.
