Guild Wars 2: Gold, Gems and real money conversions

Money is not exactly easy to come by while leveling in GW2, that much has gotten clear to most players by now. While no longer being used to "broke noob level" may play its part therein, it cannot be denied that cash flow in GW2 is considerably slower compared to other MMOs and the usual means, such as trying to make profit over the market place or grinding mobs for gold, don't work out so well either. Azuriel recently posted a great overview on how to "maximize" your coin for the time being and like him, I am slightly worried if the economy can actually recover in any significant way, given that the MP in GW2 is a global one. If 500+ people are selling the same bow as yourself, how are you ever supposed to make a profit?
