A business class ticket from Paris to Berlin gets you the same seats as an economy class ticket, with at best the bonus of the middle seat next to you being empty. (If you fly a six abreast A-319 rather than a four abreast Embraer/Bombardier jet that is.) You have the exact same “hurry up and wait” situation with passport checks, luggage checks, ticket checks, then a half-hour worth of seatbelt-on-no-laptop-no-toilet time at the start and end etc. Any traveller who wants to either work or watch a movie in peace will tell you that 4-5 hours on a train are preferable to a 1 hour flight (which is also 3.5h travel time even if you have cabs and a tight timing in the priority security lane).
