WTF is going on with Pearl Jam prices?

Why is does the new album cost £20-30 for a single stadard CD (depending on which of my local shops I go to)?

Why do I need to pay £150 if I want to see them live?

I can't believe PJ of all people have joined in with the more mainstream pop acts in the trend of making music a premium experience for the rich.

The gig tickets, ok. It's a stadium gig (boo) so it's more understandable, but I've never seen anyone price a standard CD at £20 before. And minimum £40 for single disc lp?
Please tell me this isn't the shape of things to come.

ETA: Can everyone stop arguing that prices have gone up across the board?
Dark Matter costs more than every other album in any given shop. It's not an issue related to the economy, it's an issue related to this one specific release. I'm asking why?

E 2: Looks like it's priced normally in the US which suggests it could be a UK distribution issue.
This is one of the few replies that actually furthers the discussion in a constructive way.
