Less focus on grind
It's called Eve.
Ah yes, the spreadsheet that only people who play the market game use. Which is about 5% of the playerbase. In my 1.5 years of playing EvE online, I have yet to make a spreadsheet. I have looked at some other people have made, but only as a reference.
EvE online is the exact opposite of grind. There is no skill grinding, and there are plenty of ways to make money without grinding.
The grind isn't the same as the stereotypical WoW-like's grind. That doesn't mean it doesn't exist. Currency grind instead of level/drop grind. Currency grind, for the vast majority of players, means mission grind, mining grind, or NPC bounty grind. You're doing the same things over and over for hours on end to make your numbers go up so that your character has more and better things. In most MMOs, that's exp for skill levels and rare drops. In EVE, that's ships and equipments. Worse, in most MMOs, once you get your skill levels or gear you can't lose them, ever. In EVE, you can always lose your stuff.
As you noted, very few people get into playing the market, just as very few get into running scams, confidence games, &c. Those happen to be basically the closest an EVE player comes to gaining ISK without continual grind or real money, and they represent the activity of a tiny fraction of the playerbase.
Worse, because of the game's long life and passive skill leveling, veteran players have an advantage that's well and above that of vets in most other MMOs. In GW2, for example, you can start out as a fresh player and get a toon to the level cap with full top-tier gear in less than a hundred hours. If you play Warrior, you can probably do it in less than 50. Granted, that doesn't mean you're going to be as skilled as them--you'll still get wrecked in PvP and WvW--but at least you have the same stuff available to you so that you can
learn. I played ~150 hours of EVE a few years back and barely got anywhere because of how large the gap is and how slow the grind is.
