neither of which seem to be excluded by the word "poor".

My perception of poverty is that it's a transitional state, where people are interested in leaving it.

Depending on how poor they are, the transition may be slow, and to a rich person, they may only seem to be moving between different tiers of poverty, but that doesn't mean they aren't career-minded.

In particular, I would think that the poor vs the not-poor feel more need to delay marriage and family until they feel they can better afford it after having achieved long-term educational and career goals.

There will be a lot of variation among individuals, but as a demographic generalization, those from more blue-collar communities seem to start sooner with marriage and family, and probably even have tax and other financial incentives to do so. Being rich gives you options and the confidence of upward mobility; being poor usually doesn't.
