Starting out as rogue first actually isn't that bad.
(Note when I mention zeny, I'm comparing something like 10k and 100k - actual scale for new players.)
I started with rogue when I joined. Had nothing at all. Pre TI you get a bit more money compared to other classes because you get to Steal things and NPC them. Leveling is a bit slowly since you try to finish off mobs one by one, but decent daggers/swords are incredibly cheap and affordable since you should be able to get ~200k+ as a thief from NPC'ing stuff.
When you enter TI range, you should act as if you're doing something but you actually just spend time following team and picking up loots (and using Steal skill) =p. Copy Frost Nova to easily help out team without engaging in battle. Now, since you aren't using Greed to pick up loots, probably no one will see you and complain about you.
The first 1m+ zeny I got was purely from NPC'ing loots - I saved up all the loots I had from novice -> rogue and sold them for 30 mil. I never missed the chance of picking up loots and NPC'ing them. My finger would be numb after every TI - I worked hard on it!
And after that, I used 30mil to invest and it turned into ~90mil, and then bought the most basic equips (Orc Archer Bow, Diabolus Armor, etc), which allowed me to help in parties as a Shadow Chaser.
Actually any class could pick loots and such. But if you're an archer, monk, etc you're expected to be in battle the whole time - no time to pick loots. As a rogue, you can just freeze the monsters and start picking loots (way more free time). Hopefully in low TI people are nice to let you do so, or just not even notice it. At least in Ygg, for the whole 3 months trying to get to SC people were nice and chatted with me when I looted.
So. It's an easier start to get your base zeny for your basic equips (pre 99). But if you still don't have the zeny when you're close to 3rd class, then it's a better choice to go Ranger, Sorc, etc as they're more helpful as a 3rd class. Might not be the best, but I'm just saying it's a totally do-able route you can go =D
