>But what you now get in “business class” is what you used to get in “economy” 20-30 years ago
That's nonsense. Especially in long haul flights, business class is in fact more comfortable and has more amenities than it did 20-30 years ago with lie-flat seating, on demand entertainment, etc. Traditional domestic business class is about the same as it ever was while economy has mostly seen a decrease in seat pitch. (Economy Plus--which differs by airline--is more like what regular economy used to be.)
