The NCR in fallout 2 takes a very large portion of your earnings from caravan runs, and the prices in the NCR town in fallout 2 are extremely bloated compared to the other cities in the game. 1 clip of 10mm ammo would be worth 80 caps in the Den, would be worth 150 in NCR territory. Heavy taxation is one of the most defining traits of the NCR. I was honestly very surprised how laid back the NCR was in New Vegas compared to fallout 2 Well considering that FNV takes place 40 years after Fallout 2, it's not surprising that the pricing of equipment has dropped now that there are now established manufacturing for said equipment. While it is quite true that NCR loves to levy taxes, they only do it in civilian populated areas that they have complete control over. There's really only two civilian areas that the NCR controls: Primm if you choose the NCR and the 188 outpost by the loosest of definitions.
