Well, 'yes' but also 'no'. People pay the asking price to fly - if an airline is charging $1000 to fly to Europe, that's what people pay. You don't voluntarily pay $2000 for the same seat.
Unfortunately most airlines have joined the race to the bottom, offering the absolute minimum seat pitch they can. They simply don't give passengers a real choice... it's not like they offer 33 inch pitch with fares $50 above those at 31' pitch.
Yes there are options like premium economy. But those fares are highly inflated. QF charging $5299 for premium economy to London is out of all proportion to the value of the product received. The US carriers offered a good compromise with their 'economy plus' products... $100 extra getsyou regular economy but with 6 inches extra legroom. Most other carriers don't. And from Australia I the choices to Europe are pretty limited at an almost standard 31 inches (there are a couple carriers offering a tiny bit more).
