I think it's about other factors that are correlated both with wanting to be a trader and with being willing to splurge for higher priced beers, not that one necessarily causes the other. A couple other people have mentioned this, and they're right on the money. A big one is just the amount of money you have to play with, but I also think there's an attitude component. Even within the incredibly niche group that exists on this site there's a lot of different views and that's going to reflect in how you see prices. It spans the whole spectrum from people are very casual about it and willing to drink the same great beer every night of the year to people who basically never desire to try something they've had before and look at it more like a collector or a hobbyist than as a drinker. Inevitably this is going to have a profound effect both on what price point you consider reasonable and on whether trading holds interest for you.The two are definitely related, but I'm not sure the relationship is causal the way you're looking at it.
