Wrong. You cannot balance all activities in the game, at all ranks, at all sub-factions to pay an equal amount for each activity, unless you pay the exact same amount for all regardless of complexity, duration or task.
Explore a system - 50,000 credits
Kill a pirate lord - 50,000 credits
Mine a lump of rock - 50,000 credits
Smuggle goods to an orbital - 50,000 credits
Kill 45 ships - 50,000 credits
Think that will work? You cannot balance each activity to make the same value per hour because everyone is different, plays differently and has varying amounts of time to play. I love the 'I can only play an hour a week and can't make the same amount as those who do 3-4 hours a night, it's not fair' threads.
If you watch OA's video you see he shows his PS4 account with multiple-millions in the bank and only a couple of dozen hours of game time. I've got 200+ million in credits on all my accounts and I've never exploited anything. Credits are so easy to make today that it's silly. When I began in v1.0 the mission board looked like this:

People who can't make money in Elite today are either unwilling to actually go earn it (The "I don't want to do that" crowd) or flit from place to place not building up relationships with sub-factions getting crappy payed missions as a result (Then moaning about it endlessly).
Elite is a game that takes time and actual effort. You need time to develop your skills. You need time to form relationships with sub-factions. You need time to bring up your ranks and standing. In time, you will be surrounded by allied sub-factions and can generate as much cash as you want. People who expect a Corvette and six billion in the bank on day one, bought the wrong game for their personality. They're the ones who end up posting the "I'm bored" and "grind" threads.
The other comments I see are from people with Anaconda's / Cutters / Corvettes who will say their rebuy is xx million, but they can only make 2 million a mission and it's not worth them risking their ship. So now you expect Frontier to cover your entire rebuy cost in each mission payout, so you can feel comfortable leaving the landing pad? O M G...
Back in v1.0 if you saw a player in an Anaconda, they typically had at least a Dangerous rating and you gave them a wide berth out of respect. I never heard any of them complain about rebuy.
I said it yesterday in another thread. The gap between your expectations and reality is not realities fault. Others call it grind, I call it advancement, but I'm not in a hurry to get anywhere and that's the difference. Play the game, don't game the play.
