I'm not saying ticket prices aren't too high, it just seems weird to vilify Wenger for what is a clearly true statement.
He's not talking about Arsenal specifically, he's talking about the Premier League, and there'll be very few teams who pass this money on to their fans (and the ones that do will probably get relegated because they won't be competitive). Imagine how much Man City have just agreed to pay Guardiola, and how much they'll pay their ten new £50m signings this summer. You think they're reducing ticket prices as well? Then everyone else needs to keep up.
Wenger isn't saying this is the way it should be, he's saying it's the way it inevitably will be because that's just how football works.
There is a planned protest for the Arsenal vs Leicester game. It's only going to get fans more annoyed. He should have just said no comment. Talking about being competitive my club (Southampton) seem to do fine even though we sell players to cover new ones. So the ticket price rising doesn't effect that.
