One of the things that Elite does is that it tries its hardest to prevent a buildup of wealth. Pretty much every consistent money making scheme is smashed after a few months of exploitation generating copious salt in its wake.
In the end, players are forced to farm this and that to make credits... With billion+ credit "endgame" content, this makes for a lot of pent up demand for a quick buck.. Especially those players already sitting on a billion+ credits with ships that cost 200,000 to repair after a single fight with a Thargoid
They are unlikely to want to grind out anything less than 5m per hour.
The problem comes with early game content, too..
It's far too easy to earn early game credits these days... For example, join a trade CG planned to finish within a day or two, deliver 1T of excrement or whatever they require and get rewarded 600k credits for being in the "top" (!) 100%.
Boom, you're in a basic Cobra MK III... Now if there are two such CGs primed to end on the same day you're on 1M+ credits without any appreciable effort all you need to do is collect your credits. You don't even need to go back to the CG system any more.
Bang... Straight to Type 6 Transport... Jumping a whole raft of starter content...
However, imagine if bases were REALLY expensive, you could start off with a base that has a single small pad and can store one ship.
It would start at the old Elite "Tech Level 1"
But with more money, you could build a hangar, shielding and defences (mandatory) some fancy blingaling.... biodomes roads and outer walls, flags and decals etc.
later on you could add medium or Large pads and more hangars, refuelling facilities (requiring you to bring in or purchase hydrogen etc.) repair facilities requiring materials etc.
You could even set up a trading hub which starts with few commodities and work your base up to "Tech Level 5," each one being a magnitude or two more expensive than the previous one... (the trading hub would be for your convenience/roleplay and your faction's BGS rather than make you any money more than a regular trade hub).
Anyway, it's endless...
The thing is, there should be a way to play the game at your own level and make sure progression is steady but neither glacially slow nor roadrunner quick.

That's a pretty snazzy facility you've got there. I've yet to get quite so fanciful with my own base-building. I tend to go for compact and practical myself. Kind of surprised not to see any Geodomes though - with 16 spots for planting, and no additional demand for resources, Biodomes are tough to beat.
4 biodomes suspended three-quarters of the way up the main tower.
After 1.3 that is indeed the case. before 1.3 planting did not require fuel.
I haven't bothered making a decent base this time... Too much grind. Not enough reason.
