Sure. To me an economy experience (in airline terms) is a safe seat to go from A to B on an aircraft that meets all the required safety standards. It's being allowed to board the aircraft, sit in that seat for the duration of the flight and having all relevant procedures adequately explained to me. Also expected are clean and tidy facilities. I would expect to be polite and courteous to everyone else sharing the space with me (including crew) and the same returned. And for a $40 fare I'd be very happy with that.
Even though some fares are now as cheap as a bus ride some pax haven't quite got the idea that those cheap fares are a seat to get from A to B. Want full-service? You can have it if you want to pay a full-service fare. I think aviation could do better in portraying the difference between a commuter fare and a full-service fare. They are not the same product.
