BP prices.

Yes supply and demand, and investments are good reasons for having a higher price tag. What makes them so high is my question.

Supply and demand is not a reason for higher price tags. It's the reason for all pricing, high or low.

If something has a high price tag it's because supply is low and demand is high. There are not a lot of [insert 5 gene combo] snakes, and a lot of people want them. Prices will be high.
