@greyhunter88 if you’re talking about scaling D&D scales in a terrible and highly unrealistic manner full stop. When you develop your setting you just have to factor that in.  It’s monetary system and power levels just don’t tie up.  You’re right, in order to continue to progress through the game the amount of money required continues to increase at an almost exponential rate.  Even in Forgotten Realms I find it quite jarring the amount of wealth required to realistically survive.  My group is currently level 3 and we went shopping prior to engaging with a Devil we were tracking and ended up spending something like 4000 gold on some healing potions and other sundries.  Considering that most common folk deal predominantly with copper and silver, gold being a bit like £50 notes or £100 bills – most people never really see them – the fact that we just had to spend the equivalent of £200,000 on a level 3 encounter is a little exorbitant.  But the real kicker is that such items are actually fairly easy to get hold of in terms of their availability which means that they must be commonly used items.  For that to be the case then it also follows that there must be lots of people who have lots of gold – except that doesn’t seem to be the case as can be seen by the price of the lower tiers of food and lodgings.   This is a situation that just gets worse the higher you get in level to the point where adventures start to cost in the realms of Millions of pounds equivalent in order to obtain the required equipments.  And that’s before you even start to factor in the rewards you get for completing quests – they very rarely cover the expenses involved as we are usually offered between 50 and 200 gold per character which isn’t enough to buy a useful scroll or potion for our level so we are left with no option but to take whatever we can find wherever we can find it.  These are off the shelf adventures too so it’s kind of written into the game.  I actually think that the PCs in D&D would make a more profitable living as raiders rather than adventurers because they would be less bound by where they could steal from.  I can see why they do it, it’s a way of stopping low level characters obtaining world destroying items but it can seem really silly

But all RPGs have a certain level of what is called suspension of disbelief to deal with some of the less realistic aspects of the game, this is something you just have to look past in d&d
