People getting taller and seats getting smaller

I would like the executive at Airbus who thought of the idea of standing room only flights to fly economy to Australia from the USA or Europe before adding these seats. In fact, I challenge any airline executive who runs a service to Australia to fly this route in the small seats down the back.
I would like to see economy sleeper seats before economy standing seats. There must be a way to have bunk beds or the like that still allow you to have lots of people on the flight and not taking up too much room.
I am not against getting a lot of people onto the planes. In fact, that is the best idea. Flying is a really polluting business and if we can have more people on the flights, then this is better than more flights. However, it would be nice if there was a way to get some sleep when you are stuck on a 16 hour flight.
