I'd agree with that, with the qualification that $80-100k may actually be a bit low. In the United States overall, the upper quintile of income starts at about $102k [1], so an income between $80 and $100k would place you in the upper-middle class.

However, it's important to keep in mind that the cost of living in San Francisco or New York is much higher than average. Median rent for a one-bedroom apartment is $2,795 [2] in San Francisco, that alone is over $33k a year. The SF cost of living index is 161.3 and the Manhattan cost of living index is 223.9. In other words, $100k in Manhattan is equivalent to about $45k in an average place in the US, firmly in the middle quintile. The Living Wage Project suggests it takes at least $100k to be effectively middle class in New York [3].

It's really not a perception thing, it's reality.
