The Ashes is the pinnacle of English Test cricket. Why is it a surprise to us that we cannot take 20 wickets and put the Aussies under pressure when you have medium pace bowlers trying to swing a ball in conditions where it wont move. Once that Kookaburra ball gets 10-15 overs old you get no assistance from it. You need real pace on their flat pitches to put them under the kosh as they do with us. Part of it is the conditions. You dont need spin or raw pace as you will take wickets in England at 83mph with the movement you get. We should be packing players off to play down under in the winter before the Ashes to give them a feel for Sheffield Shield cricket and flat pitches where you toil unless you can make one zip through.We'd have been better off with Mills and his back injury bowling 4 overs a day than Broad. His form is rank and he's become a coward with the bat.
In fairness most teams have competed in England lately, but I take your point. I'll say one thing to Aus they produce true pitches and let their skills do the talking. All the other countries try to doctor the pitch to favour them. That's part of the problem.

You can have some local nuance, like in England you’ll nearly always get movement in the air. But fundamentally all pitches should offer a chance with bat and ball across 5 days.
