The original economy system is way too easy to earn money, in the middle of game usually can get millions of eurodoller and no way to spend. Kind loose fun. And I’m OCD, never like round number.
After explore the game and fix out how to use wolvenkit to mod price curve and CET to mod TweakDB file.
Now happily present the loot and price adjust
 
Feature:
1 increase craft loot per level drop according to Tech_Central_Perk_2_3, original increase 25%, mod increase 100-250%, most enemy will drop 10 piece of materials and tiers according to player level.
2 adjust all craft loot to get 10 piece, including NPC loot and crate.
3 weapon price adjust 1/10. sell price curve adjust to a linear 1x,2x,3x,4x,5x  
Pistol/Revolver/AssaultRifle/SMG/Shotgun value
Tier1 200
Tier2 400
Tier3 600
Tier4 800
Tier5 1000
Melee weapon sell half like:100,200,300,400,500. I don’t think a pipe or bat can sell thousands dollar is an reasonable idea  
LMG:300, 600, 900, 1200, 1500
PrecisionSniperRifle: 400,800,1200,1600,2000
Tech and smart weapon increase 25% like 250,500,750,1000,1250
4 cloth/weapon mod/food/Scope All second hand items sell at 50
5 MQ003_painting value 100000
6 MoneyShard adjust to 500, 1000,2500,5000
7 increase cyberware price, I think be a Legendary in night city depends on cyberware, cost increase 250% and tier price like 1x,2x,3x.....
 
version 1.1 
Huge increase apartment price. since there has no rent mechanism，consider to buy out and pay in once.
corp plaza 1200000
heywood  800000
Japan town 400000
watson 100000

increase vehicle price
now top tier rayfield cost 400000 500000 

Idea to increase the motive to earn money after mid game

vehicle price can direct set in init.lua file
TweakDB:SetFlat("EconomicAssignment.v_sport1_rayfield_aerondight_player.overrideValue", 500000) --155000
TweakDB:SetFlat("EconomicAssignment.v_sport1_rayfield_caliburn_player.overrideValue", 400000)   --135000

apartment price need to use WolvenKit to mod dlc6/apart/quest/phase 
1 creat a new project
2 add dlc6_apart_wbr_jpn.questphase from asset browser to the project
3 convert dlc6_apart_wbr_jpn.questphase to json
4 open dlc6_apart_wbr_jpn.questphase.json use txt/notepad
5  search "quantity": 30000, change to 400000 or any number you like 
6  change the DB file with the same number   
TweakDB:SetFlat("EconomicAssignment.vs_apartment_dlc6_apart_wbr_jpn.overrideValue", 400000) 
done

Install:
put into game root, require CET
Shall be No side effect uninstall during game
 
Achieve file mod the price curve, db file can easily adjust by yourself.
 
Enjoy!
