I guess you mean: "Would you rather earn $800,000 and live in a neighbourhood of those earning $1,000,000, or would you rather earn $100,000 and live in a neighbourhood of those earning $80,000."
Making 80% of the median income is completely within normal ranges; it seems to me it would be barely noticeable in both cases. On the other hand, the difference between US$100,000 and US$800,000 is gigantic, it's a complete change in lifestyle and security.
Seriously, does anyone here actually find either question to pose a true dilemma?
Now reverse it. You earn $100,000. Everyone else earns $80,000. How do you feel?
Those base feelings explains consumerism and envy.
Now, I might be uncomfortable making $100K when my neighbors made $400K. That's an identifiable difference, and it would really mark me as the poor person in the neighborhood. But a 20% difference from the mean? I wouldn't even notice it.
