I agree earning money is hard, quests give little fates next to none, and next to the cost of travel repairs and teleports you lose much of it really really fast.

vendoring old items and mats give hardly anything at all.

I am struggling to keep mine over 10k atm.

Easy fix would be up the reward from fates, and vendoring goods.

The game is new so balancing will be something that happens over time.
But atm it is an issue.
