Location, location, location ... you're in the wrong place.
I'm only using a sidewinder atm but took home 5 tons of palladium and three tons of platinum in one haul today, second haul was palladium and gold I think. Anyway the two loads came to around 150k credits. The stuff is there, but if it were everywhere then the prices would have to be much lower. Who is going to pay 15k a ton for palladium if every system has tons and tons of it? It's rarity that pushes up the price.
There are traders here making over a mil per hour, so trading isn't ruined for everyone. Don't ask me how they do it, but they do it.
Don't get me wrong, if the game's not fun for you then don't play it, but maybe there's still a chance you can recover that good feeling and carry on despite the faults ... ?
