This can be a chosen business model, firms can sell to a larger market at relatively lower price vs a much more exclusive market at high prices. Capitalization costs are generally going to be lower for the firm serving the exclusive market which means higher profit margin per item sold. Assuming we don't see parts and assembly costs that substantiate these extremely high prices, perhaps a firm could cite R&D as a reason for the high price. This may or may not be true. Do we see some actual new technology in all these products?
I suppose one could research the personal financials of top management at these companies in order to to gain some insight into where money is going.
