I’d like to add that next to supply/demand, the amount of money in circulation is also relatively low; most of the silver I get from mobs/questing goes straight to class trainers, and for example flight paths are also more expensive than in retail. If people have no money, even if they would WANT to get that stack of copper to make their level 14 or so sword very much, they could not pay 50s or 1 g for it - my level 14 warrior may have 10-20 silver after training! (to make the effect of low money in circulation more concrete: if there were only 10s in the entire economy, you would never get 20s for anything). There is no huge population of level 60s yet that has no class trainer expenses anymore and floods the market with gold and demand to level their own professions or that of their alts. So if you want to make ‘easy money’, you probably need to wait a few months and try again.
That being said, you can also look at the positive side: first of all, this may be a relatively unique experience/challenge that you won’t get in retail anymore (my level 13 warrior in retail has over 100 gold), and, to quote Nobel-prize winning physicist " Ernest Rutherford — ’ We haven’t got the money , so we’ll have to think’, and that may inspire you to think of new money-making (or money-saving) strategies.
Second, if you did NOT have any gathering professions, you’d likely be even poorer (gathering allows you to make money without the expense of gaining experience and having to pay for new class skills).
And third, whenever you feel bad, you may spare some thoughts for the poor beginning herbalists, who generally must sell their stacks of peacebloom and silverleaf for much less than 14s: 2 to 3s, not much above the vendor price of 2s…
