The inflation rate in the U.S. hasn't done much damage to buying power for some years now (you can use this to see how much: http://www.westegg.com/inflation/ ), but the same can't be said for Britain and other countries in Europe as the Euro-Crisis-of-the-Week has been unfolding...
To the extent that such things influence YOUR buying power, don't forget that those same factors also affect Joe's (he doesn't get to pay in magic beans to put on his tour, after all; venues want money, transport companies want money, the folks in the band and the road crew want money, etc.).
Sometimes we let our emotions cloud our minds when thinking about economic matters. In an even relatively free market (which the U.S. and Europe are), a good or service will rise in price until it meets resistance, and then it will quickly find an equilibrium. It will not stay at that level for long, though, as at the new price demand will gradually increase again, and we repeat the cycle. That is the way the world works, always has been in this country, and for quite some time in Europe...
I just recently turned 60. If I go to the local grocery store and ask for a lower price for milk (and milk prices here in Iowa at least have gone a little nuts recently) because I've been loyally drinking it for longer than most of their other customers...
All Joe owes us is his best efforts as an artist. I believe he does that (frankly, the amount of work the man does relative to a lot of his peers blows me away). Speaking for myself, I've never been disappointed, and don't expect to be. But he doesn't owe us a longevity bonus based on when we started following him...
P.S. If anybody makes any cracks about what was life like before milk was invented ('cause at my age, I must have been there when it was) will get a poke in the snout. And I have never raised my price on that...
