You don't even play this game, yet you aim to be an armchair dev of something you no longer participate in... Great.
Inflation in WOW exists to put more emphasis on current activities than past ones, means if you became rich few expansions ago but then unsub, your gold will lose value, but if you're a new player with not a penny to your name, you have plenty of ways to get yourself started, WOW these days is very casual friendly in that aspect in comparison to some other MMOs where if you don't grind for hours until your eyes bleed or play the AH you'll never get out of the poor man's ditch. Blizzard is always thinking with "easy to start, hard to master" philosophy, it affects not only things like gearing or getting into raiding, but the "gold game" too.
