Yes/No.
You can get a California zephyer ticket from Chicago->Seattle for 160 in coach one way. That's a really good deal for 2k+ miles, generous baggage allowance, etc (if you can tolerate that).
Sleepers can go 1k+ for the 2.5d. In the winter (what I did) was 600$. I'm also not paying for the efficency. I'm paying for the experience of the hotel, meals, convenence of travel, and the ability to watch out the window.
