An even better example (same measurement scale)---Questions like this get asked quite often in practice: Is a child's income/wealth more strongly correlated with a parent's income than parent's wealth? And some variants. I think there is some literature on inference on marginals and conditional distributions, and bounds that may be useful: Search: James Heckman, Charles Manski.
