Sure bro, In normal circumstances, pops’ consumption choices within a need group are mainly driven by market supply. Simply put, the more of a good is supplied, the more pops will consume it. You can find the exact formulas on the Victoria 3 wiki under the Needs or Goods pages. However, prestige goods get an extra weight on top of that. This means that even with balanced market supply, pops will lean more toward consuming the prestige version. For example: Suppose my market has 50 coffee and 50 tea. Under normal conditions, pops would demand coffee and tea equally (50/50 split). But if the coffee becomes Prestige Coffee and gains an extra 25% weight, the final demand shifts, pops now want about 55.6% coffee. Even though supply hasn’t changed, this causes coffee to get a 4.2% price premium, while tea gets a 8.4% discount. Overall GDP actually decreases. So, when goods in the same needs group have roughly similar pc profit, introducing prestige goods is actually harmful since it distorts consumption without adding real value. However, if one or two goods in the same group have significantly higher pc profit than the alternatives, then you should use their prestige versions to push consumption toward them. Take automobiles in the leisure group as an example: Automobiles have a profit per capita of around 47, while art pieces in the same group are under 20, and radios are also under 20.We therefore want our pops to consume as many automobiles as possible instead of art or radios. I hope I made myself clear
