Ignore him. Engineering is a total gold sink. You will not make any money out of it (except maybe the cogs). It does have it's use, but not as a gold maker.
IMO, gathering proffs have always been the best gold earners, with JC being pretty good but a pig to level. Alchemy is also pretty good.
If I were starting out today I would probably pick up mining and herbing. Not only will you get a lot of gold this way, you are also getting xp for each node you gather from.
You could also go herbing and alchemy, or mining and JC, as they complement each other. But it would mean that you would have to use what you gather to skill up alchemy/JC, which would mean losing out on the gold from just going gathering.
