I remember back when I started, it was nearly impossible to find a mission that paid more than 100k. Those were typically assassination missions, the vast majority of missions paid half that or less. Haz rez didn't exist yet, powerplay didn't exist yet. The two fastest ways to make money were A-B trading (which as far as I can tell basically hasn't been touched, other than powerplay modifying prices in Alliance space and certain Empire systems), or bounty hunting in a high rez.
Massacre missions didn't exist yet, and a CZ would only pay you what, 36k for an anaconda kill? They doubled CZ payouts later to get the ones we have today.
So the high rez was where it was at. Back then if you could get more than 80k on an anaconda it was a good score, scanning one for a 100k+ bounty was a jackpot.
So to say we're not making money now when 10M to 20M missions are not that hard to find? Well... perspective, perhaps, but it seems to me our income has already been buffed by a few orders of magnitude. How much more do you want?
