It doesn't feel like it if you're living in MOST places. I bought my first house 6 months after graduating from college (2000). It cost me roughly 3x my salary at the time. I know what I pay new grads right now, and it's way more than I made back then. There's no way they can afford a house like that at 3x their salary. It's closer to 4-5x, and we are nowhere near as expensive in this area as NYC, SF, DC, etc.

133k for a family of 3 is effectively poverty wages in NYC or SF.

In less HCOL areas it is getting by, but possibly never owning a house.

Hardly the upper middle class lifestyle one imagines being lived by doctors, lawyers, etc in times past.
