A family earning $150K in NYC is probably not living the lifestyle of the Rich and Famous. But in other locations maybe.
An income of $150k is a pretty healthy in NYS. I think you’re comparing it to the wrong end of the spectrum. Of course if you compare it to millionaires it feels less than rich. Compare it to the majority of New Yorkers and you’ll have a better idea of just how well off a family with that income is.
