Well it's such a broad question. I tried to answer it a few times, but it ended up being very long winded and only covered a few edge cases.
The first one is easy - enough to pay the bills and live a decent life, including the ability to raise a family while having basic needs and some occasional extravagances met.
The second one depends on time, location and circumstance and changes from time, location and circumstance depending on which of the millions of people you are comparing. It's more of a macroeconomic / socioeconomic / philosophic question rather than a microeconomic one. The best I can answer is sometimes they would be the same, some times group A would take less than group B, sometimes group B would take less than group A. I would guess given the same location and cost of living, they would be similar.
