I agree, any money I make is instantly spent repairing the gear I broke trying to get the money! It is a bit ridiculous and I just hope SE find a way to solve it, but I don't think it's anywhere near the top of their priorities which is a little worrying/disappointing. It's not game breaking but it does mean there is little to no money left to spend. The economies effectively stuck in limbo once you reach 50 but with taxes on everything you sell there is a constant and unnecessary money sink at this point in the game.
